• My USB devices are not recognized, but they have a power

  My USB devices are not recognized, the only ones to be recognized are my mouse and keyboard. Each device is powered (motherboard works fine), but Windows 7 isn't their read (although sometimes I'll get a code 43). I have the latest chipset.

  I tried right click and uninstall each device and rebooted the computer. Nothing has fixed this.

  My external hard drive, ipod and other devices that involve the transfer of data seem to ONLY get power and nothing else.

  It is not material because all my devices work on my laptop. Also my motherboard works fine (it's the 2nd RMA) and it has been tested at the factory to make sure of him.

  I would really appreciate help with this

• How can I access the BIOS on a Pavilion p6710f when the usb keyboard is not recognized during boot?

  There is no connection to access the bios with a standard PS/2 keyboard and the USB driver does not load in time to access the bios with a combination of keys on the keyboard. I need to check the version of the BIOS and check the settings of hardware for my readers who are accessible via the BIOS. If I can't enter the appropriate key, how to enter the BIOS? Seems to be a common problem, since I see issues with some answers all over the internet. I even looked for a possible 'hidden' ps/2 connection in the case, but not joy.

  Have you tried another kbd? I recently saw a poster that is having this problem, & an another usb kbd did the trick for him. FWIW, I have a usb keyboard and mouse, and mine is trying to get into the BIOS.

• But powered USB devices are not recognized

  Randomly on my personal self built computer, readers usb ceased to recognize anything I put in them.  The strangest thing is that the devices kept under tension.  The mouse led would light up and charge the ipod.  I had to plug into an old school mouse and keyboard that do not use usb to use the machine.

  I tried:
  Unistalling/reinstalling usb drivers
  Update BIOS
  Uninstalling drivers for devices (ipod, keyboard, mouse, external hard drive)
  Updated motherboard drivers
  Compensation to reinstall Vista

  I'm really confused on what else to try.

  Data sheet:
  Q6600 2.4
  750FTW
  500 GB WD 7200 RPM hard drive
  2x2gb gskill
  EVGA 9800

  Any ideas would be useful.  Right now, the only thing I can think is to replace the motherboard, but I feel that I would not.  Thank you.

  If the answer says disabled, type

  automount enable

  Once I did, my USB keys have been recognized automatically when it is plugged.

  Why the setting has been disabled? who knows.

  tried already everything written here. When I plug my USB device (3 of them) my Windows a sad of the USB devices attached to this system has malfunctioned, and windows does not recognize it. I tried plugging it into another winXP machine, it won't work. Can you help me?

  Original title: usb malfunction

  His salvation,

  Thanks for posting your query in Microsoft Community Forum.

  1. What are the troubleshooting steps you have tried so far?
  2. If it works much earlier? If so, did you do changes on the computer before this problem?
  3. What type of USB device you are using?

  As you mentioned that the USB device does not work when plugged into a WinXP machine, it may be a problem with the device itself. In addition, the question may also arise if the currently loaded USB driver has become unstable or damaged or if your PC requires an update for problems that could conflict with a device USB and Windows.

  Therefore, I suggest you try the following methods (skip the ones that you already tried) and check if the problem persists.

  Method 1:

  Please try the fixit (s) provided below which will help you solve common problems associated with devices and USB ports.

  • Hardware devices do not work or are not detected in Windows
  • Diagnose and automatically fix the Windows USB problems

  If method 1 does not work, try Method 2.

  Method 2:

  Remove and reinstall all USB controllers.

  1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. In the list of the categories of equipment, locate and expand Bus USB controllers.
  3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
  4. Restart the computer and let the USB controllers get reinstalled.
  5. Plug in the removable USB device and test to make sure that the problem is solved.

  If the problem persists, go to method 3.

  Method 3:

  This method will install the latest drivers from device to your USB device.

  1. Click the Start button, type Windows Update in the search box, and then click Windows Update in the results pane.
  2. Click find updates. When the scan finished, click optional review updates.
  3. Click the check box next to the update, and then click install updates.
  4. If you are prompted, read the license agreement, then click I agree.
  5. Follow the instructions on the screen to download and install updates.
  6. If you are prompted, restart your computer.

  If the device fails after updating the driver, you can try to roll back the driver with its previous version.

  I get a windows notification that says-

  My office has Windows 7 32 bit and I am able to use the mouse on this computer, then the M225 is not defective.

  I tried to look for a download of update on the site of Logitech & only found:

  6.32.20 set - point it did nothing to help.

  I also tried to move the receiver to the other 2 ports USB w / still the same results.

  Are there other downloads or solutions that will help w / this problem?

  You can also try searching for devices strangers (with yellow symbols) in the Manager under the mouse devices and other pointing devices and other devices (if any). Right click and uninstall unknown devices. Then restart.

  Also try the steps below to reset the power of USB:
  (a) the laptop off, unplugged from the wall outlet.

  9. I then tried to delete the file infcache1.inf in c:\windows\system32\inf, but the problem persists.

  10. Subsequently, I tried to create another registry entry to "disable selective suspend" in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\USB by adding DWORD and assigning a binary value of 1.
