• 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.

• USB stick not recognized by Device Manager

  I have a USB drive which worked in my Vista SP2 machine for 2 years until I took it.  I tried to run recently.  Even if the machine recognizes the connection and the removal of the disc with the bong audio, it does not appear in my computer, in the Manager device (like a USB Mass Storage Device - hidden or otherwise) or in the management of Computer Management(for doing fdisk/format functions) disk.   When I insert or remove the disc, the lists of USB in Device Manager do not seem to change.

  I tried to delete infcache.1, but in vain.

  The player with the same cables and the power supply, is recoqnized and works with other systems my Vista SP2 and SP3 of XP so I can exclude it as does not.

  Dig dig into that.  The pilots were to be reloaded, I noticed there is a USB 2.0 mass storage device listed while Vista searched through the database driver.  As soon as it is loaded, the name was changed to Cypress AT2LP (chip Cypress is the controller of housing) and the drive has disappeared.  Did a search for this and it seems that it is a problem running under Vista (drive works forever and then one day things change after an update to Vista).  Rename the driver (CYUSB.sys) and then reboot didn't help.

  I took the car to the most recent machine Vista and noted that the pilot has been there for a (USBSTOR Generic USB mass storage device. (SYS).  The drive works now.   Not sure where this storage of Cypress driver came (I certainly didn't not using it), but that was the problem.

I can connect to other computers running the same operating system and he shoots very well if it is not the drive.

Ive tried all online of the easy solution like just unplug the computer and the drive and restart, remove and reinstall the drivers in the OS System. In Device Manager its reports as an unknown device under the USB bus controllers section.

• external USB drives not recognized under xp pro 64

  I bought a genuine version of XP Pro 64 to load on my computer and because Win 7 froze with drivers nVidia graphics.

  When I plug a recently bought Seagate Goflex or one of the new Western Digital external hard drives, they are not recognized.

  They do not show on my computer or disk management at all.

  They appear in Device Manager with a yellow question mark big under 'other devices '.

  I right click on the hard drive in the Device Manager to update the driver, and it always fails.

  Before ask you, these USB drives work perfectly on my other XP Home 32 System. The cables are good.

  I tried different ports, front and rear... no good.

  My system XP 64 Prp is updated w/Windows update and software chip to the motherboard.

  Strangely, I have a hard drive WD Passport USB 500 Gb one-year-old that works fine on XP 64 system.

  WD technicians say that I am the only one with this problem. PlugNPlay needs no driver, what do say.

  I also have IDE/SATA USB cable w / the power cable, I use to connect my old internal drives.

  Works fine on the XP Home 32, but I get the error "USB to ATA/ATAPI Bridge" in the device with the 64-bit System Manager.

  Yes these devices are all "turned on."

  Something is missing on the XP 64 system.

  Help is very appreciated.

  Been looking for a solution for a week now.

  Thank you.

  Hello grasshopper.

  This problem may be caused mainly by broken printer drivers, this could have been caused when you installed the updates. I suggest that you start with a restoration of the system on the computer by choosing a restore point when it was working fine.

  a. Click Start, type system restore in the search box and then in the list click on the system restore program.

  b. If you are prompted for an administrator password or a confirmation, type your password or click on continue.

  (c) in the System Restore dialog box, click on choose a different restore point and then click Next.

  d. in the list of restore points, click a restore point created before you started having the problem, and then click Next.

  e. click Finish.

  You can see the following article for reference:

  http://Windows.Microsoft.com/en-us/Windows7/products/features/system-restore

  You can also try driver restore on the computer and check if it helps.

  To roll back a driver in Windows send the driver to the version that was finally installed for the device. Restoring a driver is an easy way to return a driver for a working version when a driver update fails to fix a problem or maybe even a new problem.

  a. open the Device Manager. To do this, click Start, type device in the area Manager search and then click on Device Manager in the list programs.

  b. right click on the device for which the previous version of the driver is desired and then click Properties.

  c. click the tab drivers.

  d. click on Roll Back Driver.
