"USB Device not Recognized"

"...One of the devices attached to this computer has malfunctioned and
Windows does not recognize it..."

I already tried deleting infcache.1 but it had no effect.

Do you know what the device is? Did it ever work correctly on Vista?

I am interested in an answer to this question. My device has worked on Vista
but more times than not I get the message that is in quotes below. My device
is an external hard drive. Worked just fine on XP.

Has anyone tried this yet? http://support.microsoft.com/kb/925528

Hi ..i deleted the files and rebooted ..but the problem reappers ..after when a computer go to s3 sleep mode and wakes up... any other suggestions? Please and thanks

Use System Restore to set things back to "just the other day" or a day
earlier.

Yes...a webcam. I've tried two different webcams, at least one of which
worked fine previously in Vista (the second one (a new logitech) I just
bought two nights ago...vista compatible). Plugging in either produces the
same error. When I plug in my digital camera into the same usb port it
works fine (as a detected storage device).

the same thing happen to me my laptop when it get restored but not with the cd that come with it. after that my usb only worked for like a 5 min but than it kept saying that usb device not recognized so i rebooted with the cd that come with it and i still have the same problem i cant seem to fix it i think it my have some thing to do with updating but not sure i was wandeing if some one can help

have you maybe gotten a solution to this yet as i'm having the same problem?
thanks.

I have tried the link and it has not fixed my problem. Did anyone find
anything yet?

how do i get or open the file INFCACHE.1

I tried your suggestion, but Vista SP1 has gotten very touchy about
changes.
Got to Windows/INF/INFCACHE.1, made a copy (INFCACHE.Copy-1, the tried to
delete the orig., but after Vista went through its security dialog boxes, it
still wouldn't let me delete the file. I then tried to rename it
INFCACHE.BAK, but the same ritual transpired...Vista said no go again.

I have the same problem, I have a Lenovo T60p and a Lenovo webcam, it was
working O.K. but suddenly after I installed Vista SP1 it didn't work anymore,
so I uninstalled SP1 but, you know what? Now it didn't works neither, I'm
totally lost, can someone give me some clue to solve this issue? I know I'm
not the only one, but is Microsoft doing something to give a solution?

This solution has worked for some people with problematic USB devices:

Locate the file INFCACHE.1 in C:\Windows\inf

Right click on the INFCACHE.1 file, select Properties >Security > Edit, and give
your account full control.

Delete INFCACHE.1, or rename it to INFCACHE.1.BAK or temporarily move to your
desktop.

REBOOT

Try this fix to see if it repairs your problem, Before Posting. This
solution has worked for
some people with problematic USB and General Devices:

1. Locate the file INFCACHE.1 in C:\Windows\inf

2. Right click on the INFCACHE.1 file, select Properties >Security > Edit,
and give your account full control.

3. Delete INFCACHE.1 (Or just to be safe, rename it to INFCACHE.1.BAK or
temporarily move to your desktop but you shouldn't need to, windows doesn't
need that file to run, and if it needs to it recreates it).

4. REBOOT

I noticed this thread because my gf decided to dump some tea and it got to the laptop but it works fine (googled). I cleaned it out and all and when I got back on I got the USB Device not Recognized in slot 4, but I only got 3 slots and I dont have anything in any of them. The only thing I have currently connected to my laptop would be my charger, I unplugged that and still there. I did the INFACHE thingy when changing it completely to me, do I need to also delete or change the name of it once I give full power to me. I only gave myself full power and once I rebooted still messed up (no deletion or file name change).

Well guys I don't know how to fix the problem because I got the same problem but one thing I did figure out is, there is one program out there that read my external hard drive even when windows vista wouldn't. I had a 40g HD that just stopped working one day, i tried everything. Then I stumbled across a program called Power Data Recovery. It actually read my external HD and copied everything on it to my Computer HD. Go get this program from a torrent site, it was so cool to get everything back.

Forget about fixing the USB, it think it's a vista thing. I've tried it in 4 different computers after getting this error message and nothing would work. If you really want to save the info on the device get the Power Data Recovery program from a torrent, it's a miracle worker. I saved all 40g of files back to my harddrive.

all of a sudden i get "usb device not recognized" and just the other day i used the same devices with no problems?? any suggestions on how to fix this problem i have tried everything this is irritatin

i have had problems with usb drives for ages, i had to use file assasin to delete the INFCACHE.1 file, this is a free tool that is part of malwarebytes.
when i rebooted i now see all my usb drives, and new drives are picked up straight away, i owe you big time :)
I joined just to thank you

Make sure that if you attemp to delete the file that it actually is deleted. I could not delete/rename it without using a program to unlock the file first.

just a word of caution, any program downloaded from a file sharing site/torrent site could contain malicious malware/virus, always scan everything with both your antivirus and malware scanner before opening.

I could still see my usb drives if i used disc management and then explored them, but no new usb/external drives would be recognised, so i still had access to the data on the drives, but was a pain.

cal bears advice fixed my problem so that all new drives are recognised and all show up in "My Computer"

anyone with a similar problem should be able to see there drives by right clicking my computer/manage/disc management

I ran into this with my new ASUS P5E3 WS Pro MB (it has 12 USB ports) and Windows 7 64 . I tried all the usual stuff (uninstalling/reinstalling the USB drivers; updating the BIOS; leaving the PC off and unplugged for a few hours) but to no avail.

Somehow, I doubted this was a Windows problem because the Boot process would hang at the point where the USB hard drives were being detected by the BIOS. If I disconnected them from what I thought were the two "failing" USB ports on the MB, the PC would boot up fine. But the devices would still get unrecognized if I replugged them in after Windows was up and running.

Anyway, I found that if I unplugged all by USB devices, booted up, then replugged the two drives first, they were detected fine and the drivers got loaded. I then gradually attached the rest of my other devices and, bingo, the last one came up with the same error, even though I connected it via a different USB port.

So, it finally dawned on me that the problem was likely due to the fact that I had a lot of USB devices (3 HD drives, webcam, keyboard, video tuner card, 2 UPS's, printer, scanner, card reader etc.) and that the combined power draw on the USB bus must be exceeding its capacity. So, I added an external, self-powered 7 port USB Hub and used it for some of the devices.

The problem went away!!!!!

Can somebody please shed some light on this for me? I have been running Windows Vista Home Premium 32 bit SP2 on an eMachine H5270 with an Athlon LE1640 2.7 GHz processor. All updates have been successfully installed. The system has worked without any hiccups until I decided to try and 'sync'y mobile phone (Samsung SCH r351). All peripheral usb devices work properly and are recognized in Device Manager. The phone has a removable 4Gb memory card that is discoverable when plugged directly into the media center on the front of the computer. Countless discussions with Samsung techs have reiterated that this phone does "not" require the installation of special drivers to be discovered by the pc. As I said previously
all other usb peripheral devices plugged into the back and front of this unit work properly. I have tried to rectify this situation by applying many of the remedies found in other posts on this and other forums including the "shut down/unplug, delete infcache, uninstall devices in device manager move devices around, and plug all devices directly into the back USB ports. All attempts have resulted in the same result.
I have the following devices installed on this computer; Canon MP 210 printer, Microsoft Laser wired mouse, Bluetooth dongle transmitter. Any help would be greatly appreciated as this is beginning to drive me slightly insane...yeah I know that's like being 'slightly pregnant' :-))

Try this:
1. Unplug (power cord) your PC and shutdown.
2. Unplug all your USB devices from your PC (and, heck, any power supplies as well)
3. Wait 30 minutes or more !
4. Plug in your essential USB devices (keyboard, mouse).
5. Plug in your PC, turn it on.
6. Pop in the rest of your USB devices.

Oh thank God I almost gone crazy to figure it out! Thank you guys.

The issue is with the registry... When I first encountered this issue last week I searched all over the internet for a solution and no one had a permanent fix. Being the troubleshooter that I am I decided to take deep look into the problem and you'll be surprised at what I found.

I first tried the power down and remove/reconnect all USB devices and sure enough they came back working but over night I ended up having the same issue the next morning.

I tried repairing the registry but all of a sudden I had no access to make changes to it and I remember I never had an issue before so why now???

So this is what I did:

1.) You must first enable the administrator account in order for you to be able to do this by doing the following --> Open the command prompt in administrator mode by right-clicking and choosing “Run as administrator” and type the following command and finish by pressing enter:

net user administrator /active:yes

You should see a message that the command completed successfully. Log out, and you’ll now see the Administrator account as a choice. (Note that this also works on Windows 7.)

2.) Now log in as the administrator and remove the USB related items/drivers from "Computer Management".

3.) Go to "Control Panel" and double click "Power Options", then click on (depending on what you have it set to - mine is set to high performance) "Change plan settings", then "Change advance power settings" and scroll down "USB settings" and expand it, also expand "USB selective suspend setting" and set them to "Disabled", click "Apply" and then "OK" to close the popup window.

4.) Go to the "Windows" folder and locate the "regedit.exe" file, right click it and select properties. Go to the "Security" tab and take full ownership of it. Apply or save changes you just made and close all windows.

5.) Now hold the button down a few seconds until the unit powers off. Once off wait a few seconds and turn it back on. Log back in to windows and you should see or notice the USB drivers installing or loading.

6.) Once it has finished, test your ports, they should work with no problems.

7.) If they are okay, make a backup of your registry just in case you ever run across this problem again.

8.) Also make sure to run a deep virus scan to make sure you do not have a java scripts viruses running in the background. I use "Microsoft Security Essentials" because who else knows their system better than anyone else??? That's right, Mr. Bill Gates himself and I trust his product to the max and besides, it is completely "FREE"!!!

Enjoy and I hope this helps... any questions feel free to respond. Have a nice day, OTAY!!!

just incase anyone still has this problem i have found the simplest solution (worked for me) just switch the usb port to either one in the back or front. just offering one possible solution

[2milehigh]

AHHHH! I FOUND IT! (well, for me only, maybe for you?!)

So I've been doing my research on this topic because I've had this conflict happening for the last couple of weeks. My problem was that my Toshiba laptop wasn't recognizing my SAMSUNG CAPTIVATE. I was unable to put music or download pics from my phone (it was able to before).

I tried all the solutions, unplug laptop (something customer care will tell you), uninstall and reinstall drivers, reformat pc, download pc fix its and finally dump water over the keyboard. None of these work and I didn't try the water one.

WHat I found is that in my DEVICE Manager I had 3 ATI I/O Communications Processors running, USB 1.1 OHCI controller USB 1.1 OHCI controller and USB 2.0 EHCI controller.

I played with the disabling option and disabled 2 of the 3 controllers. Leaving 1 operatiing. I then tried every usb port to see if it would recognized. After performing this on all the combinations I finally found the right one and now my SAMSUNG CAPTIVATE is working flawlessly.

I'm sure this will work for any other devices.

The only problem I have now is that it won't work on the 2.0port which kinda sucks. But I'm glad everything is working and I can add music and stuff to my phone.

Hope this Helps everyone! good luck!

Certain phone connectivity software from vendors such as Samsung, Nokia, Bora, Novatel, and Sony may cause your device not to be recognized. If you have such software on your computer:

Uninstall your Samsung, Nokia, Bora, Novatel, or Sony phone connectivity software and test

i also did what the dude ^ up there said about the whole registry key thing and it seems to be working, before, sometimes when i plugged in my iPhone it would work like once in a blue moon, i havent unplugged and replugged the USB cable from the computer just incase it doesnt charge. FML i spend roughly 2 hours a day tryna get my phone to start charging maybe i just need to change the cable but i only bought the cable recently and its been working fine. could be my phone is old but i cant be asked to go to Apple and i doubt they will replace it.
