Uninstall the drivers in Device Manager, and then reboot. Windows should automatically install some drivers.

i uninstall the drivers reboot but nothing happened ...same error Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47)
Is it necessary to have the latest bios ?

all my usb devices works just fine under windows 7. so this is not a bug. just a thought. reboot with the device still connected. does your problem occur without using the safely remove? if its set for quick removal, we don't have to use safely remove to diconnect the device.

It is possible there is something corrupted with the OS.
Have you tried running sfc /scannow? This may not fix anything, but worth a try.

If numerous devices are giving similar errors on one system but are fine on another,, then it is one of these things....

Corrupted OS

Corrupted/Bad Drivers

Bad Motherboard

Other Bad Hardware

This is not a Win 7 problem, to the best of my knowledge.

EDIT: Yes, as you are having problems,, it could be worth upgrading to the latest BIOS.
Also, the latest Chipset Drivers

It might even be worth trying the following,,, uninstall all drivers through Uninstall Programs and then reinstall them. I am not saying this will not make things worse or break something else. but it might help,,, maybe.

You can try these Chipset Drivers from Intel (9.​​1.​​1.​​1025)
