I have a HP Elitebook 8440P running Windows XP Pro SP3. I installed it on my docking station and everything went smooth for a while. Last week, my mouse and any other USB devices stoped working sudenly... It was working fine on my laptop itself but nothing on my docking station. LCD attached monitor works and same for LAN and PS2 keyboard.

I updated the BIOS, Chipset, Video Drivers, also changed my docking station by a brand new one but the problem still comes back.

I also noticed something in Device Manager... A Generic USB Root Hub has an error on it, a Yellow/Orange exclamation mark. I tried to update that driver but no luck. Windows is unable to process it. This seems to be the problem but can't fix it. I may only re-image my laptop but for me, I need to avoid that since I have so many apps installed on it.

If anybody has any advice, I'll take it!
