USB Devices is not detected! Why?

• Bluetooth randomly, and now the device is not detected

  Hello

  I bought a laptop 15-J108la want a month ago (8.1 Windows 64). I also bought a Microsoft bluetooth mouse to use with it.

  I first noticed mouse stoped working randomly, maybe 2 times a day. Sometimes it was enough to turn off and on again to get it back, but sometimes I had to reboot.

  I updated the driver bluetooth (Bluetooth 4.0 Driver Intel, 2014-01-18, Version 3.1), the problem persisted, but seemed less frequent.

  After you install an update for the wireless network card device manager today announced that Intel Bluetooth 4.0 device has been failing. Try to dissable and reactivate, but the device has simply disappeared. Now the Device Manager indicates an "unknown USB device" with error 43, and Bluetooth devices are not detected, no matter how many times I reboot.

  Any help will be much appreciated.

  Using the generic drivers provided with windows 8.1 instead of Intel drivers, finally solved the problem.

  No more intermittent, peripheral stranger either.

  I was foolish enough to install the latest driver updated to Intel to see if it has addressed the problem, but it was as bad as before. I had to go back to the generic drivers, once again and voila: everything works like a charm again.

  I hope this helps others.

  And Intel: come on, you should do better!

• Since the L7680 installation my usb ports are not detected...

  It seems that something in the registry has been changed.  My Western Digital Passport (mass storage device) is not detected is not my SanDisk Micro (2G).  Western Digital will work in the USB from the printer, but don't the SanDisk.  I've lost the use of all of my USB ports on my computer processor and montor.  They used to work before installation.  I uninstalled and reinstalled, I check startup items in MSCONFIG.

  I read on the Microsoft support page which the hkey_local_machine\system\currentControlSet\Control...

  should be set to activate, but I do not have this folder in XP.

  Western Digital does not know what is happening, or not SanDisk.  HP really gave me the run around way to uninstall and reinstall, but I didn't get an answer that solves the problem.

  It seems to me that since it was drivers from HP which caused my other unit to pass unnoticed, HP should be able to tell me how to solve this problem.  I do too much research for a new product.  I know I'm very frustrated, and since this is a new printer I still have time to take it for something that's going to work.  I had a Dell that has worked well, I wanted to just an upgrade.  I guess I could have updated by Dell.

  Just about the evacuation, someone has an idea what the fix is for my USB not detected ports that have been replaced by the reader on this printer?

  I added a new HP printer to my set all my ports no longer works. None of my flash drives or removable hard disks worked. I tried everything and then read "ports must be updated". My computer is older than three years and the ports of origin are 1.1 and are of most new USB 2.0 devices. Long story short, I went to microcenter and bought new ports ($11.00) and add them to my computer. All ports are now functional.

• HELP - All the USB device does not not - Vista Ultimate

  I have a desktop P4 computer and ran on Vista Ultimate for more than 1 year (window updated constantly). Everything worked smoothly until one night, all my USB devices don't work anymore. Based on the Device Manager, the USB are ok, check my BIOS, everything remains unchanged.

  now, I got tired of reinstalling the same operating system and at the end of the installation, all USB devices do not work.

  Please can someone advise what should I do to recover my devices USB working again.

  It is the motherboard or the operating system has problems?

• 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.

• USB ports do not detection devices

  Hello

  My USB ports are sensors not when I their connection. I hear the noise, which indicates a device has been connected, but when my laptop is trying to install the driver, it gives me an error Code 39.

  I see an icon in Device Manager yellow triangle-shaped when a device has been plugged in. I tried to uninstall and reinstall my driver and running fixit (said mass storage device USB has a driver problem and can't fix), but no luck.

  I'm running Windows 7 Home Basic Edition and tried to insert a USB Hard Seagate Drive, Kingston and a Sandisk USB key (they all work fine on other computers).

  Hello Marilou,

  Thank you for your response.

  What is the brand and model of your laptop?

  I appreciate your efforts to resolve the issue.

  I also appreciate the fact that you ran Microsoft fixit.

  Method 1:
  Uninstall and reinstall the USB controllers and check. Please follow these steps:

  a. press Windows + R keys, type devmgmt.msc in the run window and press ENTER.
  (b) in Device Manager, expand 'USB Bus controllers'.
  c. a device under "In Bus USB controllers" right click and click on Uninstall.
  d. perform the same step for other devices. Once completed, restart the computer.

  All USB controllers will reinstall automatically.

  If this does not help, use method 2.

  Method 2:
  Turn off the "selective suspend" feature of the USB hub driver and check the issue. Please follow these steps:

  a. press Windows + R keys, type regedit into the run window and press ENTER.
  b. look for, and then click the following key in the registry:

  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\USB

  (c) in the "Edit" menu, point to 'New' and then click 'DWORD'.
  d. Type "DisableSelectiveSuspend" and press ENTER.
  e. in the "Edit" menu, click on 'change'.
  f. type '1', and then click ok.

  Important notes:
  Serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:

• SanDisk Cruzer Blade USB key can not detect properly by Win 7 64 bit

  Hi all:

  I have this problem on and outside.

  This time, it's ok and next time can be bad that the USB device is unable to detect Win 7 64 bit. It's OK to Win Xp all the time.

  I have referred to as the previous posts for this problem and remove the VID_0781 by REG_EDIT, also try to uninstall the device from the hardware in the computer and re - install the device. I also did the replacement of usbstor.inf in c:\windows\inf to another subfolder.

  from c:\windows\.

  The result is intermittent it's Ok this time and not okay at other times. It's really wasting a lot of time to try this or that, and the result is intermittent.

  Can anyone or Sandisk people leave a good and permanent solution to this problem?

  Thank you and best regards,

  tangsuan

  Hi all:

  I want to update this solution for this problem of Sandisk support.

  This solution may be different from one case to another, but if you have installed Samsung KIES in PC, then most likely it is the solution.

  If you kill the KiesTrayAgent.exe, the Sandisk can be detected smoothly whenever you plug it into my laptop.

  Thanks and respect of the best.

• 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.

  * Original title: Ext usb devices appearing is not in my computer

  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.

  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.
