hello everyone

i am hoping someone could help me with this issue i started having. it seems none of my USB devices will install sucessfully on my PC. when i plug in one it instantly tell me it was unable to install it. at first i though it was just the one device but i have a USB mouse and keyboard too so i tried them in one of the other USB ports and it failed the same way too i also tried uninstalling the USB root hubs and controllers in device manager but they will not install too. i ruled out that it is not a hardware problem because my USB keyboard will let me go into the BIOS and still works. the only way i was able to get my keyboard and mouse back was to remote in and perform a system restore. the only things i could find were to replace the usbscan.sys with a new one i got from another computer i have but no effect. so other than backing up everything and reinstalling windows does anyone else have any other suggestions?

Thank you

would check on motheboard maker to see if there is a new bios that could correct this or driver update for chipset

I had this problem on a laptop once and the way I fixed it was to reset the BIOS to defaults. When it booted the USB ports worked fine. If you try this remember to go back into BIOS and set your desired preferences again.

defaulting the BIOS didn't work and i installed that latest BIOS over a year ago and after i installed it i had no problems with USB

but thanks for the suggestions

thanks but nothing in that link worked as well.
reinstall chipset drivers
it made me go throught the troubleshooter but the only thing it was able to come up with was to make the printer that wasn't working the default printer
USB root hubs. already tried that and lost my keyboard and mouse and had to perform a system restore via remote desktop to get them back

if you read my OP you will find out it is not just a printer its any new USB devices i try to connect that fail. i even tried moving a USB device that is working on my computer like my keyboard to a different USB port and it failed installing the driver but i connect it back to the USB port it was in before and the keyboard will work again

realy strange behaviour would check every usb connector carefullly for bent pins or a wire that connect to those and the motherboard look like it made intermittent contact try the voltmeter test with power then power off to read impedance on each port , when you plug something in usb device

i don't believe it would be that as well. i use VMware and was able to install a new USB device on the VM successfully
