• 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

• The mistake that the USB device is not recognized... Help, please...

  I am trying to connect to Simple external storage drive and once I followed all the steps (only 2) Windows XP gave me a message that the USB device is not recognized or it malfunctioned.

• 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.

  Hello

  If you can not embedded USB to work then you can disable it in the BIOS and the device
  Manager and use a USB expansion card that is not expensive.

  Check the BIOS settings.

  ACer laptop WIn 7 amd a8 quadruple-heart: when I log about 1 T external usb 2.0 or 3.0 hardrives or key USB 64 G,.
  Device Manager displays the devices, but they do not appear in the list of computers. I have other ext hardrives and the keys that operate without problem.
  I have to go to disk management and see that they appear but they do not have a drive label assigned.
  Then I have to give it a label letter manually it will appear under my computer.

  I tried the same features on a laptop HP with Windows 7 without all these questions.

  Thanks RTierra

  I have found a more permanent solution. At the command prompt, type Diskpart

  type

  automount

  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.

  I hope this helps others.

• Canon LBP 2900 B: USB cable is not recognized by Setup on Windows 7

  The USB is not recognized by the Installer before once. I was in windows 7 and downloaded the drivers from the official Canon Web site, so I've upgraded to windows 10 but a few reasons that I rolled back to windows 7 but now the printer driver is lost so I decided to reinstall. I've seen a lot of discussions on this and in this respect Canon website but nothing works at all. Here we are with an image where the device and printers can detect the Cannon printer but the installation program can detect it at all.

  

  Also, I tried these things:

  • Reinstall the software.
  • Tried to update the existing drivers, and then restart the computer.
  • Changed the serial port.
  • Download the software again.
  • Print management > delete data...

  Hello Siddharth,

  Thanks for posting your query in Microsoft Community and appreciate your efforts to solve this issue.

  Have you tried to connect to any other USB device? Has been the result even?

  I understand that the USB device is detected by your computer, but could not install the driver and get the message "cannot recognize the USB connection. The question may 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. This can also occur if your USB controllers may have become unstable or corrupt. So, I would suggest trying the following steps 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.

  Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.

• device not recognized by Windows

  Hello

  I have a problem with my camera, I saw a lot of posts here of a similar question, so do not know how to see that I have not seen any solution.

  When I connect my camera to the USB port, Windows will try to install the drivers but complain that the device is not recognized.

  I can see new driver added to 'my computer' under memory card format, but it is not accessible

  If I try to delete the driver of drivers installed, it will reinstall with the same problem

  If I connect using tips I've seen here (hold down and press the Center button) it will be recognized, but only for this session, moreover, when I do, I can't see or delete songs I've stored there before, but I can add new songs.

  In any case, I can play those songs.

  The format of the device or reolve somehow?

  On the device, go to

  Settings > USBMode > select MSC.

  That will force a permanent connection of MSC. You will not see the content of the PSG. First, you could reformat and start over.

  Go to settings > Format > select Yes

  I advise you to update the firmware while you are here.

• Video device record to the clock store is not recognized on Windows 8

  Original title: Windows 8 video glitch

  Windows 8 works well except the storage of the clock of my video recording device is not recognized when I plug in the USB cable.  The same clock works very well with a Windows 7 system.  There is no error message or of any indication of Windows 8 that the unit is plugged.  No driver not supplied with the clock.  Windows 7 lists of storage of the clock as a "generic Compact Flash USB Device".  Apparently the driver compatible with the clock is missing from Windows 8, or there may be another problem.

  Hi Donald,.

  Please contact Microsoft Community. I understand that peripheral storage of the clock of this recording video is not detected on your computer Windows 8. I've surely you will help solve this problem.

  To better understand the issue, I would need more information on your side.

  1. Faced with any issue when connecting other USB devices?
  2. What is the make and model of recording video clock?

  This problem might have occurred because of these reasons:
  1. corrupted USB or port driver.
  2 damaged material.
  3. wrong settings.

  Try the steps listed here and see if it helps:

  Method 1:
  I suggest to connect the storage device to the clock of the video recording on another USB port and check if it is detected.

  Method 2:
  If the problem persists, I suggest you run the troubleshooter of material and to check if the basic material settings are set correctly.

  a. press the keys Windows + C on your keyboard to show the charms.

  b. type Troubleshooting , and then click solving problems under settings.

  c. now, type Hardware Troubleshooter in the search option.

  d. click convenience hardware store to run the troubleshooter.

  Method 3:
  If the problem persists, I suggest you to download and install the latest driver for chipset on the site of computer manufacturer and check if it helps. Alternatively, you can install all Windows updates available including optional updates.
