If not then I would go to device manager in an admin account and at the top the tree select your computer and then Action, Scan for Hardware Changes.

I uninstalled USB drivers and devices in device manager after following instructions from a an article on Microsofts site. They dont work in safe mode, and they dont work after selecting repair my computer or whatever its called. Ive been searching the internet extensively and found no satisfying solutions. In fact Im becoming really nervous that I messed something up for good after reading somewhere that deleting the host controllers makes the USB ports unrecognized by the motherboard. I have a single PS2 slot and will buy a mouse tomorrow, but I still dont know what I have to do to fix the USB problem even if that mouse works.:( HELP EDIT: Windows 7,AsRock H97m Pro4 mobo, Intel 3.0 USB drivers previously installed. I dont agree. The wounds remain. Time - the mind, protecting its sanity - covers them with some scar tissue and the pain lessens, but it is never gone. Along with what Condobloke suggested make sure your mouse and keyboard are not in any blue USB 3 ports. I cant do a system restore because the mouse and keyboard dont work after the post screen. I dont really need to back anything up as I had just done a fresh install of windows the day before. Assuming I get a PS2 mouse to work, what do I need to do to get the USB devices to work again if we assume everything in device manager regarding USBs was uninstalled I want to avoid reinstalling the OS. ![]() Its ridiculous that they suggest uninstalling USB devices when something like this could happen. Theres absolutely nothing I can think of to gain control except getting a PS2 mouse. What would people without a PS2 port do Its basically inextricable, this makes no sense. Someone just tell me how to get the host controller and root hub and all the others working again when I do manage to get the mouse working. Thx. You should mouse and keyboard should function if on USB 2 though I believe the kernel of Fatdog also has USB 3 support. It can be created on any Windows 7 computer so if you have a functioning Windows 7 computer create the disk and do a System Restore. If you do not have a Windows 7 computer available you can use a Windows 7 install disk and at this window select repair computer. Is there a way to restore the drivers from within windows if I get the mouse to work I need to reinstall the host controller drivers, I dont know what Im looking for though - the Intel USB drivers.
