My USB mouse & keyboard was working on and off. This happens regularly on my Windows Vista. So I decided to delete my USB Hub drivers and reinstall. However not thinking, after deleting those drivers, of course my mouse and keyboard stopped working. Now when I turn on my computer, neither my mouse or keyboard works. However they do work in the BIOS, and I've went into safe mode, did not work there, went to last known good configuration, did not work there. Does anyone have an idea what I can do?
