Holly Bananas, i need help! USBs not working

[jgpaiva]

For some reason, my usbs have just gone to hell!
They just won't work, i connect the mouse to it and it gets no power!
On system -> device manager, i get 5 usb devices that just won't install. I unninstall them, they are installed automatically and they get the "could not be installed error".

Please help...

I presume you have gone through the usual reboot etc.

Have you tried using system restore to go back a few hours to see if they work with an older version of the registry?

Does your BIOS have USB device detection (mine says on POST screen USB Devices: 1 Keyboards, 1 Mouse, 1 Hard Disc) - if so does it still detect the devices? If it did before and doesn't now it looks like a hardware fault, if it did and still does it looks like a corruption in windows somewhere.

If not the only other thing I can suggest is a minimal fresh install of Windows on a spare small partition to check it isn't a hardware fault (it isn't impossible for USB controllers to fail).

If it tracks down to windows can you completely uninstall all USB devices including hubs and controllers and then try and rebuild from the device manager?

Also check you have no disc errors (run an offline CHKDSK on your system disk) - one of the driver files may have been damaged.

Thank you Carol! You're the best!
System restore worked great, apparently the problem must have been caused by the install of virtual box. Not that it's good that the program gave me trouble, but at least it's fixed now.
Now, i shall try to install it again
Thanks again
