As of yesterday, 6 of the 7 USB ports on my Dell XPS Dimension 9150 (XP) stopped working.I had my printer, wireless mouse and wired keyboard plugged into the backI had my 4-port USB hub and my headphones plugged into the front; a camera cable was attached to the hub but not to the camera.Only
one port on the back works now. My USB hub is now plugged into that
and I have my mouse and keyboard attached. I can also plug in my
printer and headphones at the same time and everything will work. My
camera cable will not work in any port.Here is what I have tried so far, with no success:I unplugged everything and tried just my keyboard in each port, same with my mouse. Only the one port works.I rebooted with only the keyboard and mouse.I checked device manager to ensure everything was working properly.I uninstalled all the root hubs and had Windows reinstall it on reboot.I did a system restore to a week ago. (Everything was fine on Friday night.)I searched for updated drivers. (None found.)I flashed the BIOS.I made sure the power management does not allow Windows to turn off the hubs.What
else can I try? I have one other device I need to attach directly to
the machine instead of through the hub else it won't work.thanks!
