This is really odd and I work with PCs for years and know abit about them. I have a TOSHIBA P200-1JV ( great laptop by the way). It has 6 USB ports. All are in the system of the Vista control panel. Only the 4 right hand side ones work. I have tried all sorts of USB devices in the 2 that dont. Here is where gets is really strange, my Palm 750 phone works, but thats it. My mouse, external drive dont etc. I have even removed them for the system and rebooted and this has not fixed the problem. Help!
