Usb Ports Stopped Working


This error happens suddenly. All the usb devices and the ports are working, they are activated on the bios, but they don't work when the windows starts. In the device manager it shows an exclamation on usb controllers an says about code 10.

If i remove all the devices and then "check for new hardware", windows recognize all of them and everything works fine. But is just restart the pc and the error returns. I've already updated the bios from motherboard (updated it from usb, worked 100%), but when entering in windows. I've tried to look for some drivers, but didn't find nothing about drivers for my motherboard. Is a gigabyte ga-ma69vm-s2 (which is supported by win7) and i'm using windows 7 x64

Plugging Usb Keyboard & Mouse Into Different Usb Ports

I have a usb keyboard and mouse. Recently, i had to relocate my computer, so the keyboard and mouse were unplugged. My question is: if i plug the keyboard and mouse back, but not into the original usb ports, will this cause windows 7 to create a new hardware profile, or any other registry changes as a result?

Problems With Usb Ports

Basically i'm having problems with the usb ports. The ones on the back of the motherboard and the connectors inside on the motherboard. Some usb devices will work great, others won't work at all.

Example: i have 2 sandisk cruzer flash drives. If i plug the 4gb in windows picks it up right away and asks what i would like to do (open folder etc. ) However, when i plug the 2gb flash drive in windows does nothing. The cruzer 2gb shows up in "devices & printers" but i can't do anything with it. I can do this with every usb port on the motherboard. Same results. The 2gb flash drive works. I've tried it on another computer.

I noticed this when i tried inserting a memory card into my card reader. "Devices & printers" knows that there is a pro-gear xm-4u card reader attached, but won't do anything with it. I borrowed 2 other card readers from work and i get the same end result. Windows shows them in "devices & printers" but i can't do anything with them.

I'm using a fresh copy of windows 7 64bit. Installed it about 8 days ago. I upgraded the bios right after windows was installed. However i assumed the usb port wouldn't be a problem so i didn't checked them before upgrading the bios.

Usb Ports Problem

Im using win 7 32-bit and a asus p4vp-mx mobo

1. I plugged in my pen-drive (tried several of them), computer shows "this device can perform faster" and ask me to plug into usb 2. 0. As far as i know, p4vp-mx usb ports are usb 2. 0

2. When i transfer file into it, it stops at approx 1/4 of the process. After that, it says removable drive cannot be located even though i replugged it

3. Replug, says need to reformat.
4. Tried to reformat, failed.

5. Need to plug into other pc to reformat it before can be use again. The cycle goes on and on.
 
Is this a virus prob or win7 prob? Edit: forgot to mention that my last windows update was on daylight savings time which was release somewhere in feb 2008 if im not mistaken. Now everytime i restart, my computer resets to 1/1/2002.

Usb Ports Will Not Work

This is a new build. Asus p6t mb, 12gig mem, win 7. All works fantastic except cannot get usb ports to recognize any input. Have logitec 15 keyboard, flash drives, card reader, jam lab, usb hub and others. Device manager shows that all 8 ports are working, all drivers up to date. I have tried the usual methods to fix. Click off the power management box (win 7), unplugged power source few minutes.

Delete drivers and reinstall. Nothing, now here is the weird thing, i can plug in usb devices in all ports and nothing is recognized. Have downloaded all win 7 drivers from the vendors, these devices light up, they get power, but will not work.

Issue With Usb Ports

Like many other users a i too am having an issue with usb ports in a brand new computer build and clean windows 7 install.

I have tried many of the "fixes" on this board -
 Unplugging the computer
 Uninstalling the usb drivers
 Installing the latest chipset drivers
 Uninstalling ghost devices

Nothing seems to work. Anyway, i built the pc, installed windows, installed the latest intel chip drivers (ver 9. 1. 1. 1020), installed the latest f3 bios, uninstalled the latest intel driver and installed what came on the cd with the mobo and still cannot get the front usb or the card-reader's usb port to work with usb sticks. I even reverted back to ver 9. 1. 1. 1013) chipset drivers with no luck.

I even changed which internal port i had the card reader connected to. The funny thing is the card reader is working fine in both of the internal ports. I can read/write sd and compact flash cards just fine. However the usb port on the card will not work with a usb memory stick, external hdd, or usb flash card reader.

Neither will the front side usb ports on the case. Does anyone know if this is an os issue? A mobo issue, or something else. I am tired of installing an uninstalling things.

I just purchased the following hardware/software:

Gigabyte ga-p55-ud4p (rev 1. 0) mobo
Intel core i7 860 2. 8 ghz
Rosewill case with front side usb/firewire
Ocz stealthxstream 700w power supply
Powercolor hd readon 4350 video card (not nvidia)
Nippon labs internal card reader
Windows 7 professional 64bit.

Hp Tx2000 Usb Ports Issues

The usb ports seem to send power to an attached device (e.g. A blackberry) for an instant then go dead. The usb hubs show up in device manager and uninstalling / reinstalling them doesn't make them work. The driver for the screen digitizer (tablet) is wacom and installs properly but when accessing tablet properties control panel a dialog "supported tablet not found on the system": the digitizer does not show on device manager either.

Bluetooth shows up in device manager under network adapters, but not in control panel webcam doesn't show up in device manager. I heard about using the acer-chicony driver and no help for me there. With all these issues i wonder if this is a hardware problem - but with details like the usb port registering for an instant then goign dead i hope theres a driver / software / config solution.

Switching Usb Ports During Backup

I am running a backup and using a usb port in the back of my pc with a hub. After 7 hours i am only 58% done. Can i just unplug the usb cable to the external hard drive and plug into a 2. 0 port in the front of my machine during backup? Also, this is not my first backup and i would like to only backup new or altered files. Is this possible?

Usb Ports Disabled After Every Boot Up

I have been running windows 7 for a few days. Been quite happy with it. Suddenly, my usb stuff started failing. After several attempts to locate the culprit i found they had error messages in the device manager. I re-enabled the ports and presto. They all work again. Great, then i rebooted. All disabled again. I changed/unchecked the power saving mode after reading up about that and it is staying unchecked. But the ports are still disabling every time i reboot. Running a 2 year old hp pavilian. 64 bit win7 installed intel core 2 quad. 3 gig ram. 2 external dvd burners, usb keyboard, wireless mouse. Nothing special.

Usb Ports Are Not Working In Front

I noticed yesterday that my computer was taking really long time to respond, and after restarting it my computer took 30 minutes to get to the desktop. So i reinstalled windows 7 thinking it would fix my problem. It didn't. It still was taking 30 minuets to load to the desk top, nut now my usb ports in the front won't recognize my flash drive, my digital camera, or my web cam. Every thing flash or kicks on when i plug them in, but my computer doesn't pick them up at all. My computer is really sick and i have no idea how to fix it. Any suggestions?

Anytime i plug a usb device in i get a message saying that the device is not recognized. In the device manager under the usb section i get an "unknown device" with or without something plugged in. Ive tried quite a few different drivers and read 100's of forum posts trying to help solve the problem. No one seems to have an answer and lots of people seem to be having the same problem any help would be appreciated.

Usb Ports Suddenly Stop Working

Well the problem is that all the usb ports of my computer alienware aurora (dell gaming edition computer) have stopped working in windows. Yesterday they were functioning normally, i didn't install anything or changed any configuration. Today i turned my pc on and the usb keyboard was recognized in my bios set up(i can use my keyboard only in the bios set up) and all the usb ports functioned as well while i'm in bios set up but when windows 7 starts the light in the keyboard goes off and it stop functioning as well as the usb mouse and any other ports so i can't type my password on the log in screen of windows.

I guess it is a software problem but since i cannot enter in windows i can't do anything to fix it(my pc doesn't have any ports for old keyboards and mouse).

Error Code 52 - Usb Ports Not Working

I have recently purchased a new laptop with windows 7 and had no initial problems connecting usb devices (mouse, hard drive, camera etc. ) To the ports. Since installing a number of windows updates none of my usb ports will now recognize any hardware that is connected to them.

The error code is quoted as follows "windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52".

I have been into device manager and notice that each usb icon has a yellow exclamation mark icon next to it. I have uninstalled each usb port and scanned for hardware changes which has no positive affect. I have also tried to 'update driver software' in device manager and again this tells me that the driver is up-to-date for each usb port.

Front Usb Ports Overloading Flash Drives

My computer is an hp pavilion purchased this past christmas at best buy. About a month ago, after plugging my flash drive in to one of the usb ports and noticing that it didn't recognize that any device had been plugged into the system, i pulled the flash drive out with the intention of trying it over again. The flash drive was very hot to the touch, close to the point of being painfully so. I immediately tried plugging it into my laptop, with no success.

My wife then got her old flash drive and tried, just to see if it was a fluke, but the same problem occurred. The usb port ate her flash drive. It wasn't burning hot upon being removed, but the drive would no longer read when i plugged it into the laptop. It would recognize that a usb device had been inserted, but would be unable to discern what type of usb device it was and, as a result, fail to read it at all.

I have no idea whether the front usbs are shorted out or if this might be some kind of odd software issue. A friend of my wife seems to think the usb drivers need to be reloaded, but i still wonder if it isn't a short in the physical circuit. Has anyone ever heard of this happening? If so, what is the best solution? I've already contacted hp about it and they want me to mail them the tower for a complete system reload - back to factory conditions. I really want to avoid that with all the data i have on this computer, if at all possible.

Usb Not Working Properly - Ports Randomly Stop Working

I ran the windows 7 upgrade advisor before upgrading on my gateway gt5678 and it did not mention any compatibility issues with my drivers. After upgrading i noticed my usb peripherals are not working properly. My external usb hard disk shuts down about 12% of the way into a windows backup. If i plug in my ipod, there is a good chance it won't be recognized.

Same thing happens with usb memory sticks. If i plug them in, they either work or they don't; it is inconsistent. When one device fails, none of the ports work until i reboot. This has been a pain, because i have several vms i use for development, and half of the time they fail to copy to my usb hard drive.

I opened up device manager and noticed the following for nvida nforce system management:
[Conflicting device list]
Input/output range 4900 - 493f used by:
Motherboard resources

I ran cpu-z to see what chipset my motherboard uses:
Chipset: geforce 7100
South-bridge: nforce 630i

I confirmed on gateway's support website that the chipset is geforce 7100. I went to nvidia's website to get the latest drivers and installed the ones for windows 7 geforce 7100. I am still having the same problems. I am not a hardware guy; i'm a software guy, so i think i am trying the wrong things. I haven't seen a conflicting i/o range in seven years.

Com Ports Change Itself

I will try and keep this short. I was using the com 1 on my hp to key my radio. That computer died and i got a new one that has no com ports so i got a usb to serial adapter and it seemed to work but then on its own it will key the radio 3 or 4 times then switch com ports on me. I can reconfigure it and reboot and then it works (for a period of time) then does it again. Any ideas? 

Other devises are working fine on 2 other adapters but they have software that controls them where this one being used for push to talk on the radio (for digital communications) does not it is just relying on the voltage change from dtr dts and ground to key a small circuit that in turn keys the radio, when the voltage drops back to normal it unkeys the radio. Thanks for taking the time to read this, and feel free to email direct to email removed for privacy if you like.

Xp Mode Cannot Find Lpt1 Ports

I have just purchased a new pc which came with windows 7 pro installed. This machine had no lpt ports fitted as supplied. I use a very old dos based accounts programme which will only print to lpt1. I understand that i cant run dos programmes in win 7 so i have set up a windows virtual pc to run in xp mode and my old dos software runs just fine.

I have fitted a lpt pci card and win 7 has detected this but has called it lpt3 and i have successfully installed an equaly old epson printer to it. My problem is that i cannot get this port to install on the virtual xp mode system and even if i manage that can i rename it to lpt1 and install a printer to it. Any help would be much appreciated even if its just to tell me that what i am trying to do is not possible.

Printer Installation Problem - Can't Access Ports

We have been installation windows 7 on a subset of our machines to test it out, seems to work fine for the most part, but just ran into a printer snag. We installed a hp deskjet 3600 printer driver on lpt1:, all went well, now, i want to select the printer and change the port setting to usb. The funny thing is that when i click on the printer and select "printer properties" the dialog will not display. Its not grayed out, etc. Its like the computer is doing something, but never finishes.

On all my other machines, i can access the "printer properties" menu item no problem, and this is a must since i need to play with the port and other advanced settings. Finally, this is different from the "properties" menu item, that one does come up, but useless. Also, tried clicking on the printer icon itself and getting to the printer properties dialog like that, again doesn't work, just seems that no matter what can't get it to display.

As a test case, i installed the same driver on another machine with a fresh install of windows 7 almost mimicking the install of the troubled machine and i can click the "printer properties" tab.
Any ideas about this and why it won't display? We have tried everything simple like pulling the usb cable, uninstalling the printer, re-installing the printer driver, and all permutations. Its like no matter what, whenever you select the printer you can't display the "printer properties" dialog.

Failed Ir Usb Cir Install Usb Card Reader Problem

I have a reasonably clean and fresh w7 pro 32 install on a fujitsu lifebook t series tablet. I recently bought an epraizer card reader to enable me to import photos from a cf.

On installing it for the first time, the driver installs failed. The driver it failed on was the ehome infrared receiver (usbcir). To the best of my knowledge, the device does not contain an ir device of any sort.

I inserted the same device in an xp machine and it worked fine. Have i:

(A) wasted my money, (b) encountered a known problem with a simple fix (do tell), or
(C) tripped over something nasty i don't want to know about (see a)?

Identify Usb 2.0 Cables / Test Usb Cable Speed

Is there a way to tell if a cable is usb 2. 0? Or better yet, is there a was to test usb tables to find their transfer rate?I have a huge supply of usb cables to go through. Some are clearly marked usb on the connector or on the wire itself. But most cables have no markings to indicate their spec. I've searched a lot and found no good and reliable way to test them. I've seen recommendations to try to use the cables to transfer large files and watch the speed. But that does not seem reliable and won't work since i have all sorts of different end connectors to test.

And i've seen some spec information such as there will not be a ferrite connector on 2. 0 cables. And 2. 0 cables won't be longer than 3m. But i am looking for something that will tell me definitively if the cables are 2. 0 spec. And better yet, what is the actual transfer speed since some cables are better than others. I would prefer some marking or physical characteristics on the cable that would tell the version. But i am open to (hopefully inexpensive) test equipment too. Some sort of terminator-like tester would be ideal.

Usb Flash Drive - Usb Device Is Not Recognized

I have tried 4 different usb flash drives from different manufacturers and my usb hard drive from western digital. Windows 7 recognizes it until i start transferring files. Then it can't find the drive. When i unplug it and plug it back in, i get a notification that the usb device is not recognized. After i restart the computer, it does the same thing all over again. I ran vista before windows 7 and never had this problem. I am very frustrated. I must have access to my flash & external drives or windows 7 is useless to me.

Usb Suspend:usb Device Not Entering Suspend

I purchased windows 7 as soon as it was available in stores. I installed it and after using it for a few days, i noticed that my usb devices weren't selectively suspending to save power like they were in the release candidate of windows 7. I left it alone 'till now. I just reinstalled windows 7, thinking it maybe some software or driver that i had installed that was causing this problem. So i didn't install any drivers or software and ran the power efficiency diagnostics report, and all of my usb devices have the error: usb suspend:usb device not entering suspend.

Can you please help me with this? If you need to know, i am using an asus m4a79 deluxe mobo.

Usb Connection

I am having trouble with a usb connection. This is what it says. One of the usb devices attache to this computer has malfunctioned and windows does not recognize it this happens whenever i put in a flash-drive. Or even when i try to download pictures from my camera. I have 2 label printers and 2 printers connected to my computer. This didn't start happening until i got 1 of the  new printers. I have tried putting the flash drives on a different computer and it works just fine.

I have replaced all the cables with 2. 0. I took the computer to staples to ask them and when they connected it it was fine. So i don't know what else i can do. Only one of my label printers is a serial port, all others are usb. This is a desktop. I have tried even putting the flash-drive in the back of the computer in one of the empty ports but i get the same error. I hope i don't sound too stupid. It is driving me crazy. Can you help me?

Bsod - Usb Vulnerability

This happened to me 1 week ago. The night before my computer was working fine. Turns it on the next morning and my usb mouse and usb wireless adapter were not working. I unplugged the mouse and plugged it back in and it worked. Then did the same to my wireless adapter. As soon as i plugged it in, i had a bsod and the computer restarted in less than 1 second.

The problems arrived when i checked my hotmail and found loads of spam being sent out from it and found that it was china sending these e-mails out to random people. Few days later i looked on my computer and noticed that applications had been replaced with chinese characters and that china had gone into my computer (i looked for this in the mcaffee logs on my computer).

My computer is fully up to date with updates from microsoft and there are no registry flaws at all. Any help here with this matter? As far as i am aware there was a vulnerability for this that had supposed to have been patched up.
