  Hello

  Since you said it worked very well recently, I'll try to do a system restore at this point in time.

  See this link: http://windows.microsoft.com/en-us/windows7/products/features/system-restore?SignedIn=1

  In addition, see the response of the Meghmala and follow the instructions listed there. I think that the three method might be the best of the bunch for you, but they have all the right steps.

  b. expandBus USB controllers.

• Device USB error: USB device not recognized

  For a week to 10 days I could not connect my USB drive to the USB port. Also my keyboard and mouse stopped working because I was using a USB hub. It must have been a few Windows Vista update recently which caused this problem with USB devices. It does not recognize the USB devices. I can use the USB device on my laptop mini where I have Windows 7.

  Microsoft is going to solve the problem in Windows Vista. There should be no reason that we cannot use USB devices and before 10 days ago, it was not a problem.

  Thank you for your help.

  Hi NRuss,

  1. have you checked if the devices are getting detected in Device Manager?

  Step 1: Tips for solving problems of USB devices

  http://Windows.Microsoft.com/en-us/Windows-Vista/tips-for-solving-problems-with-USB-devices

  Step 2: Uninstall all USB device manager entries

  a. Click Start and typedevmgmt.msc and then click OK. Device Manager opens.

  b. expand Bus USB controllers.

  c. the first USB controller under Bus USB controllers right click and then click on uninstall to remove it.

  d. Repeat step 4 for each USB controller is listed under Bus USB controllers.

  e. restart the computer. After the computer starts, Windows will automatically check for changes on the hardware and reinstall all USB controllers that you uninstalled.

  f. check the USB device to see if it works

  Hope this information is useful.

• His number disappointed + B500 USB device not recognized at startup

  Hello

  We have 2 B500

  whenever I'm starting, after loading windows they give me an error "USB device not recognized" I don't know what to do any help will be greatly appreciated as it is strange that both machines are giving the same error.

  also on one of the machines the sound does not work, I tried to get out of trouble, the diagnostic says the speakers are working properly, but not her out at all.

  I'm kind of disappointed by these questions, we always buy at Dell, but we thought we would give Lenovo a chance, the machines were barely a few months, when the problem started.

  advice please?

  That error usually comes up when a non bootable USB device is connected. Check the Bios and make sure that the CD drive and HARD drive are loading first. That should solve your problem. If this is not the case, make sure that you don't have any USB stick or disk external HARD connected until the PC load.

• USB device not recognized... Unplug the thing does NOT work

  It baffles me that THOUSANDS of people have this problem, or a variant of it, and no ONE at Microsoft or elsewhere also offers a real solution. Unless of course you want to count the method "unplug your computer", which is the most foolish band-aid for a problem I never heard, even if it works for a lot of people (most). I, unfortunately, am one of those for which the "disconnect" method magic does NOT work. I tried everything what all other posters and responder suggested (BIOS upgrade, change Legacy BIOS definition Enable to disable to activate again, driver updates, uninstall all USB, full power down and restart hours later, use CMD prompt to show only devices, etc.) and do not know what else to try. I would really like to see a REAL answer as to the cause of the majority of the questions posted about the USB error outside the usual "restore your settings, use your restore disk, unplug it, replace your USB key, etc etc etc. HEY! MICROSOFT! SOLVE THE PROBLEM! OR, Hey, here's an idea, a news for you, I'm sure that... don't they exude products until they have been tested (NO! I mean really, fully tested [see XBox 360 RROD])

  In case anyone reading this is a real working solution, I'm on a Toshiba A135-S2386, Vista Home, and each USB port is unusable on any device. All ports feeds the device and noise sounds to indicate that a USB device was attached and then proceeds to the display of the error "USB device not recognized" and shows and shows an unknown device connected. It does this for any USB device.

  FINALLY: PLEASE PLEASE PLEASE DO NOT POST A REPLY IF YOU USED THE METHOD OF "DISCONNECT", AND IT WORKED. Grats to you for fixing your computer, but I can just not read another 400 posts of "wow it worked for me great fantastic" when it does NOT work for everyone. I need something new and real. (Sorry to be all grumpy, but I'm tired of these kinds of problems from companies making billions off the coast of junk, defective, half finished, produced a car!) "You listen to Bill?)

  UPDATE: just ran a scan of the system file Confirmation via an administrator command prompt and it's clean...
  ALSO - was not that before, but now whenever I do a complete power down / reboot thing that it gives me a "Bad Checksum" error and I have to reset the date and time in the BIOS. I need to change the battery in MB? As I said it did not have this before and the USB error was produced, but could this be the problem? Bad battery MB CMOS?

  The bios of your motherboard is probably damaged.

  step 1. See if you can find a previous version of the bios of your motherboard and return date of the bios.

  step 2. Find the latest version of the bios of your motherboard and update your bios.

  Do not use a registered version of your current version.

  To check the problem is the motherboard or operating system. find something like a live Ubuntu CD

  http://www.Ubuntu.com/desktop/get-Ubuntu/download.

  or

  Make a Ultimate Boot CD for Windows

  http://www.UBCD4Win.com/index.htm you are using windows xp or borrow a copy to UBD4WIN.

  Both of the above run in memory (does not load on hard drive.

  Both a bit slow, but are excellent tools.

  Works like a normal computer.

  If you can see you USB devices, magicjack, ETC. your BIOS is not corrupt or motherboard problem.

  In normal windows if you see not the USB devices, magicjack, etc your windows install is corrupt.

  Reload Windows of difficulty.

  If you you do not see the magicjack, USB devices, ETC., your BIOS is corrupt motherboard or other problem.

  Redo your BIOS as described above.

  All other unwanted do not work , he was done !
