I am running Vista, service pack 2, 32-bit on a Dell Dimension XPD601.
I attached a Coby MP3 player to my computer, and my mouse and keyboard stopped working. I restarted the machine, minus the Coby, and the keyboard and mouse worked again.
I reconnected the Coby, and the keyboard and mouse don't work again. I removed the Coby, restarted, but this time still no keyboard or mouse.
I checked Device manager, and there was no listing for human interface device.
I have tried system restore, to two time points prior to the installation of the Coby, but both restore attempts failed.
I have flashed the bios, but still no results.
How do I restore Human Interface Device to the Device Manager.
