• HP Pavilion DV7 2270us: USB Ports not working on HP Pavilion DV7

  I get the USB device not recognized on all USB ports on my laptop.

  I am running Windows 7 (recently did a restore to clean computer) service pack 1.

  I refreshed the BIOS

  I tried to remove all the drivers, stop, remove the battery and restart

  I tried refreshing all USB drivers

  I tried to adjust the power settings to make sure that all power mode on the economy USB devices has been disabled

  Still no luck. From time to time I can plug something and it will work a bit then it becomes disconnected. I think this could be a hardware problem as no intervention software worked. All advice appreciated!

• USB ports not recognized anymore

  I have Vista.  USB ports and ports that accept cards camera no longer recognize them.  Scanner can be moved from USB port to the USB port and works but "Explorer" does not show that they exist.  How to recognize camera cards (mainly) as they did before?  Windows offers device (camera card) has a problem, but this isn't the case.  Card works so executed through camera (USB cable to the USB port) in two different cases with two different cameras.  Also plugged on the USP port scanner is not recognized by the function 'Explorer' but actually works very well.

  Hello ghpots,

  ·         What happens when connect cards camera on USB ports, it installs the device drivers?

  ·         What are the changes that you made to your computer, since it has stopped working.

  When you connect your devices to the USB ports, check the status of the device in the Device Manager. Check if you see a yellow fringe or exclamations in the Device Manager.

  I suggest that you remove and then reinstall all USB controllers.

  To remove and reinstall all USB controllers, follow these steps:

  1. click on start, type Device Manager and open the Device Manager.

  2 right-click every device under the Bus USB controllers node and then click on uninstall to remove them one at a time.

  3. restart the computer and reinstall the USB controllers.

  Plug in the removable USB storage device and test to make sure that the problem is solved.

  Check the Device Manager to see if the unit under section USB or other devices. To do this, follow the procedures below:

  Method 1:

  1. click on Start, right click computerand select Properties .

  2. click on Device Manager.

  3. click on the (+) sign next to Universal Serial Bus controllers and next to the peripheral plus other section.

  Look for the USB device under the Universal Serial Bus controllers, or under the other devices section.

  4. If the unit is under Bus USB controllers or other devices, click on the reference to the 'unknown' device name, and then click Uninstall to remove the device.

  5. close Device Manager, and then restart the computer.

  6. If the USB device that has problems with software and it has not already been installed, install the software, now follow the planned manufacturer of the directives.

  7 reconnect the USB device that had issues and test to see if it works.

  The unit should now work correctly. Continue if the device name is not found in the Device Manager.

  Method 2: There may be a problem with the USB port. Try connecting to a different USB port. If the USB device is displayed in Device Manager after plugging the cable in a different port, then uninstall and reinstall the software of USB device driver.

  Method 3: Check the manufacturer of the device for support if the device is still unable to display.

• Satellite C650 - USB ports not recognized in Device Manager

  When I turned off my cell phone, I lose the use of my two USB ports. The only way I can get back them is to use Device Manager

  Go into the Manager of peripheral devices, Bus USB controllers, there are 6 x Intel ICH9 Family USB Universal Host controller 2 x Intel ICH9 Family USB2 Enhanced Host Controllers and 7 x USB hub root. When I lose the USB ports, USB root hubs seem to disappear, and the only way I can get back them is to uninstall the controllers and then right-click Universal Serial Bus Conrollers for "scan for changes on the hardware. This brings back the root hubs and USB ports work fine... until the computer turns off again.

  Someone at - he encountered this problem and managed to resolve it? Its a hassle to have to go through the uninstall it / Reinstall procedure each time. Your advice will be appreciated.

  Hey Buddy,

  You use the version preinstalled Windows from Toshiba or did you install your own version? I don't see any information about the BONES in your ad...
  Theoretically, it could be a software problem so ports USB work correctly if they recognized in Device Manager

  You should also try to update the Web from Toshiba site chipset driver. Maybe it helps.
  Otherwise, I could imagine that the update of the BIOS can also operate and this update you can get on the Web from Toshiba site too.

  The problem with coming back to win 7 is may or may not win 7 drivers.  I would contact Compaq to see if there is win 7 drivers.

• Satellite P10-304: USB Ports not recognize anything

  I have a Satellite P10-304 and the USB ports not recognize anything that are attached to them. Device Manager tells me that they are enbaled and works correctly. What can be wrong with them or what can I do?

  Hello

  One of my friends has the same unit on the work and everything works perfectly. It uses the USB hub too and have many external devices connected to the unit.

  By the way: something like who can occur if the external device is not removed correctly use safely remove hardware option. If you try to connect any other device after that in most cases it is not recognized at all. In this case, you can restart the device or remove ports from the Device Manager and use the hardware detection to find them again.

  Good bye
