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 Flash Drive Driver Install Failed / Not Recognized

I plugged in a flash drive to my laptop the other day and i got the plug and play message, it downloaded the driver but the installation failed. Now windows 7 will not even recognize that the flash drive is plugged in or try to install the driver again. The flash drive still works on my main computer just fine and other usb devices including other flash drivers work just fine on this laptop. Device manager and computer management under administrative tools do not register it as being plugged in either.

I could not find a way to check if maybe the driver did install and was corrupted. Is there anything i can do?

Usb Flash Drive Error - Volume Does Not Contain Recognized File System

I plugged in my usb flash drive into a computer using windows 7. It always prompts me to scan and fix or cancel. I canceled every time, but i got annoyed with it popping up every time, so i told it to scan and fix. A loading screen came up so i patiently waited. After completion it asks to format my usb flash drive. I can't format it though because i have homework files and all my other personal files on there. So i canceled the format, but every time i plug it into my computer it asks t format it. I even plugged it into a computer running on windows xp and it wanted to format it.

When i try to run it without formatting it it says, "e: is not accessible. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted. " My question is, what did windows 7 do to my flash drive and how do i recover my data?

Usb Flash Drive Device Not Working

I have about 3-4 flash drives. 2 from kingston and 2 from transcend. I'm having trouble using the 4 gb transcend flash drive and 32 gb kingston flash drive. Scenario 1> the transcend pen-drive: the device is not recognized after i plug it in and when i go to open it from start>computer  it gives me error message"please insert a disk into the removable disk. "

Troubleshooting done:

1> change the drive letter from disk management wizard(start> right click on computer>manage).

2> checked for usbstor value(3).

3> checked on numerous computers(xp, vista, windows 7)

4> deleting usb root hubs and controllers and allowing windows to re-install them.

5> updated bios. Scenario 2> with the 32gb kingston flash drive.

Unlike the transcend pendrive, this seems to behave very strangely. The problem arises after i tried to format the drive. Though data can be copied, it cannot be viewed. (Be it any files music, video, documents)troubleshooting done: same as the previous one.

Device Malfunctioned Error Code - 43 - Usb Device Not Recognized

I purchased a new computer with windows 7.initially my ipod worked fine with this computer. It still charges the ipod but nothing else. In addition it will not work on my old computer.

1. I have completely uninstalled and reinstalled itunes.

2. I reset the device losing all of my music.

3. I have gone to device manager and the ipod shows up as unkown device. I have stopped the device driver and rebooted.

4. I have tried to have attached to my old computer update and i receive the exact same error and usb not recognized message.

5. Other devices work fine on the usb hub, in addition i have tried the other usb hub.

All of the above measures have failed. This all started when i was having problems updating my music to the ipod, and i chose the restore function on the summary page of the itunes software, with the device attached, and recognized. Since then nothing? Initially when the device was attached after the restore option was chosen, i got need to attach to a 2. 0 usb  high speed hub, error message? It is a 2. 0 usb high speed device. I have reviewed other questions in this forum, on apples forums, all with the same results, nothing.

I just purchased a toshiba notebook satellite l500. It has stickers shown windows 7 on the notebook but i can't find the windows cd in the packaging. I have alot of problems with this notebook till i can't do my homework and run basic tasks.

Problem 2) when i plug in my imation apollo 2. 5" portable hdd (25 phdd-500gb), the windows shown 'usb device not recognized'. I tried using ms fix tool but still doesn't work.

Problem 3) i added a password into my account which is also administrator account. The same password works when pc starting up but it doesn't work when i tried to switch pc back from sleeping mode with the same password. It shown me 'account being disabled'. I see no option in the control panel for me to activate this account again.

Problem 4) whenever i switch on my notebook, the screen shown 'system preparation tool 3. 14'. What is this for and is it recommended to have this? If not, pls advice how to switch this off at windows 7. I found some procedure to switch off at windows vista but not 7. Apologize for i can't differential between toshiba's problem or window's problem. All i know, i have some frustration to get things done with this new notebook and windows 7.

I never needed to download drivers from anyone to make them work on any other os . I just plug them in and the work . The 1st time. Not after trying all things that don't.

Usb Flash Hard Drives Not Recognized

Since purchasing my computer, i've been able to use the various usb drives for other hardware such as wireless internet, hauppage tv reception, and wireless mouse/keyboard. However, any attempt at reading an external flash drive (then larger external hard drive) on all of the ports the drive is not successful. The drive appears in the device manager and is appropriately named, it is also listed in the disk management window as disc 5 (underneath the various sd drive ports and whatnot-one of which appears to be assigned the name of usb external hard drive when in fact it is not).

Upon attempt to reassign a drive path/letter the message appears that "disk management console view not up to date", but restarting does no good. Dell support is not supportive and claim it is a software problem because the ports work for other devices.

Lg Touch Phone Usb Device Not Recognized

I plugged my new lg touch phone into my laptop to load music. Drivers were automatically loaded, except one failed. The one that failed to load wasn't a problem because the other two drivers were the ones needed to identify the phone in windows and load the music. The problem is the alert ("usb device not recognized) keeps popping up and i can't get it to turn off.

I replugged in the phone and that cleared it while the phone was plugged in and for 5 minutes after but then the alerts started up again. They flash every few minutes. I've closed the connection, it doesn't show on the task tray but in the alert menu under windows it continues to list "usb device note recognized. " How can i clear this alert?

I've rebooted and completely shut down the laptop to no avail.

Intermittent Usb Device Not Recognized Problem

I have a dell precision m6500 laptop in a docking station with a usb keyboard and mouse attached running win 7 pro 64-bit. Most of the time, the machine works fine without any issues but occasionally, windows goes into this tight loop where every few seconds, it pops up the dreaded usb device not recognized balloon-even though i have not added/changed and usb device on the machine. I have tried disabling the device, uninstalling the driver, etc. But nothing i do seems to correct the problem. Please help because this is driving me crazy.

Dell Webcam - Usb Device Is Not Recognized

My new laptop had been running great for the first week or so, but today problems started occurring. Right now i'm having problems with the built in webcam, the screen is black and i'm not sure if the mic is picking up sound or not. I keep getting a warning that the "usb device is not recognized" even though i don't have a usb plugged in, so i'm under the assumption that this problem relates to my webcam issues.

It comes up almost every five seconds and is really bothering me. I have also seen a message come up that i have a problem with my dell dock. I don't know what this means or what the problem is, but i know that it probably is important and possibly relates to my other issues. I'm new to the whole windows 7 operating system because i've been using xp for years so if you can walk me through what to do that would be great.

Ipod Classic (80gb) Usb Device Not Recognized

I have recently upgraded to a new laptop (acer aspire 5738g) running windows 7. I have successfully transfered my itunes library across and have installed itunes (x64) which is running fine. When i plug my ipod classic (80gb) into a usb port i get a message saying 'usb device not recognized'. I have managed to get it working once but when i did, i got an error message saying 'this drive could run faster' or something along those lines. I have tried other usb devices and all seem to work fine so i'm assuming its the drivers for the ipod or a compatibility issue with 7 and itunes.

I have uninstalled and reinstalled itunes, have reinstalled the usb drivers and have scoured the net for a fix but wo is still me! I have waited patiently for a fix from either microsoft or apple but as yet nothing. It seems that this is a wide spread problem. Does anyone have any ideas as what was once a slightly annoying problem is turning into a right royal pain in the a$$.

Usb Drive Not Recognized After Reboot

I have a windows 7 64-bit system. I connected my maxtor 500gb usb drive while the pc was on and it recognized the drive using the default windows driver. Seagate, which owns maxtor, does not have a 64 bit driver for this drive. Seagate and microsoft say the drive should work with the windows driver. It was working beautifully.

Then i re-booted my system. Upon windows re-start, the drive came up as "usb device not recognized". In device manager it is a yellow icon next to "unknown device". I removed the usb cable and re-plugged it to no avail. I then removed the drive's power cord and plugged it back in. The drive was instantly recognized again.

What is happening on a re-boot to mess up the usb connection? How can this be resolved? I don't want to have to pull the power cord on every re-boot.

Ide Hard Drive (usb 2.0) Not Recognized At Computer Startup

Ide hard drive in external enclosure (usb 2. 0) not recognized by windows 7 at computer startup, but recognized if it is rebooted after windows 7 is done loading. I have a western digital 500gb pata (ide) hard drive in an enclosure. I leave the enclosure on at all times since it has a cooling fan.

However, if for whatever reason i need to reboot my system, windows 7 never recognizes this drive unless i turn off and on my enclosure. Once i reboot my enclosure, windows 7 recognizes the drive and tries to autoplay. I would like w7 to recognize my drive at startup so that i don't have to reboot my enclosure every time i reboot my computer. What can i do to fix this?

Usb Flash Drives Device Driver Software Not Successfully Installed

Usb external drives, usb flash drives "device driver software not successfully installed". Acer and windows 7 problem. Not sure which one i am more frustrated with. Acer or microsoft trying to get decent customer service out of either seems so difficult. Ok, its a common enough issue.

I've seen this everywhere in other forums and every finger points back to microsoft. Usb flash drives, jump drives, memory sticks, thumb drives, whatever they are called, they don't work on my acer laptop. Yet all work perfectly well on my vista pc and my work xp. So they are not damaged. Also a freecom external 1tb usb drive. Doesn't work on win 7.

I have an acer 5338 (less than a year old) which sadly as windows as an oem so microsoft aren't interested in helping saying it's acer's problem. Acers website doesn't even acknowledge existence of the the model laptop i have which makes contacting them for a solution physically impossible (anyone got a phone number or email address>). Anyway they had a free upgrade to win 7.

(Oh you cannot imagine how much i wish i hadn't. ). So i upgraded. And all usb memory devices suddenly don't work. Ll of them try to load drivers then give up with the error message. Just to get the usual answers out of the way!I've tested the usb ports. All work. I've uninstalled all the usb ports and let win 7 re-install them. No problem i've cleared the file that keeps records of drives.

I did a new clean install. Nothing changed. Can't upgrade chipset drivers. Won't let me, says i don't need them every drive appears during the boot screen. Every drive appears in device manager but showing as fault. Updated, installed, deleted, re-installed every driver on the planet. Tried the 'regedit' solution suggested elsewhere, fragged my laptop, lucky i system restored up. Doesn't appear on disk management so can't deal with any drive letter conflicts. Have no virus.

Have only one firewall installed. Have prayed have hit the flipping thing have pleaded have pretended to cry. Not interested. So, i am hoping against hope that someone has a solution to this issue. I have a vague thought that it could be something to do with 'ports' and port settings. That, i am afraid is a closed book to me, so please, geniuses everywhere, give me something new to try! Or a way to speak to a human at acer!

Usb Flash Drive Problem

I have windows 7 on a dell inspiron 1525 (originally came with vista). Every time i use my flash drive to read or play files, or even just view files on windows explorer, it freezes up. The only way to fix it is to unplug it and wait, otherwise it will just sit there with a blank white screen. This never happened on my xp desktop. But what i wanted to do was back up my system. It seems to work until it reaches 25%.

That's when it freezes again. This also happens with a blank cd. The only external memory (besides an external hdd [i never tried that]) that works is a sd card. I don't have a high enough memory card so i'm stuck. I need something to back my system on.

Can't Erase From The Usb Flash Drive

I attempted to install a chrome os(portable) on to my 8gb flash drive, but it didn't work. But i can't erase it from the flash drive now because windows vista recognizes it as a unformatted drive and now reads as 720mb. I did not try to format the drive because i don't know if it will do further damage.

The software i used to install the .img file is win32diskimager (https://launchpad.net/win32-image-writer/+download), i used this software along with power iso all the time so i figured i knew how to install something from a flash drive i was wrong, the only thing i can possibly think of is a software program to decipher the type of .img it is and delete it.

Unable Eject Usb Flash Drive

I've recently installed windows 7 on my system and since then i am having problem in ejecting my usb devices. When ever i click on eject the pop-up notification in the system tray says "your hardware can be removed safely" but the light on the flash drive still keeps blinking and i can still access the drive. Even if i repeat the process of clicking on safely remove hardware at various location(system tray, devices and printers, my computer. ) I am still able to access the device despite the message "you can safely remove the hardware)

My flash drive has even produced bad sectors because of unplugging the device ignoring this.

Readyboost On 16gb Usb Flash Drive

Windows recommends reserving 15. 125 gb for ready boost on a 16 gb usb flash drive, but if i set it to that capacity the drive usage indicator turns from blue to red. Even though the stripe turns red it still shows a small amount of space available on the drive, but only around 570 mb. Should i ignore this red stripe or dial back the reserved space for ready boost? If i dedicate the entire device to ready boost it also turns red.

Will ready boost still function properly if the indicator is red when dedicated entirely to ready boost?

Autoplay Not Working For Usb Flash Drive

Auto-play works smoothly on my windows 7 pro 64 bit installation with one exception. For some reason, it will not initiate with my usb drive (formatted fat32). The drive shows up in explorer just fine. I have already gone into the control panel for autoplay, and changed just about every setting imaginable, to no avail.

This is not a huge deal, except that it would be nice for this device to have the same behavior as other autoplay type devices. Oh, by the way, autoplay works just fine with this usb thumb drive on my notebook.

Usb Flash Drive Hidden In Explorer

I can see my f: drive in my admin account; but when i switch to mys daily user account -  any usb flash drive plugged in is invisible - if i manually type f: into the path box - it lists the drive contents just fine.

I've used admin, comp management, disks and the drive shows up as f: without any problems, if i re-name it to x: it then shows up in explorer; but swap it for another usb flash drive and its again invisible. Switch to admin account and its plainly visible. I had a look with tune-up utilities and the 'customizable drive displays' option for f: is ticked. I can hide and display other drives this way; but f: never appears.

Note i have a card reader, so drives g: h: k: are also always visible; dvd drive is e: and i have 2 hard drives c: & d: plus a hidden recovery drive, i can rename that to x: and it shows and hides - but still no f: drive. Where is the 'display / hide drives' option in win 7. I used to be able to do this in tweak ui on xp; biy do we miss that utility.

Installing Win 7 To A Usb Flash Drive

I own an asus eee and i have been wanting to install windows 7 ultimate onto it for a while now. Unfortunately the hard drive only has around 3. 7 gb of memory in it. I was wondering if i could possibly install it to an 8 gb usb flash drive instead. Earlier today i was trying to figure out why the usb drive wasn't on the list of locations to install to, and in my desperation i accidentally formatted my entire hdd, rendering the laptop useless unless i can install an os onto it. I have tried google-ing and it constantly keeps displaying how to install from a usb flash drive. I just want to install windows 7 onto my lappy toppy without buying any extra hardware.
