We have a Dell Precision T3400 that has been used in our warehouse for the past year. Last week the user logged a support call as the USB mouse wasn't working. After looking into the issue, we decided to wipe the machine, and reinstall a clean Windows XP SP3 build, and load all of the up to date Dell drivers on.
However, even after all of this, we can't seem to get a mouse working on the system. Plugging a USB mouse in, does cause Windows to detect new hardware, and it successfully installs as a 'Dell Optical Mouse', or other mouse models we've tried. The mouse appears to work for a few seconds while the driver is installing, but about 5 seconds after the hardware has finished instaling, the mouse just stops working, and the pointer remains stuck in the same position on the screen.
We've tried 3 different mice, which we've tested on another system and know they work, we've tried removing all of the USB Human Inteface devices, rebooting, and letting Windows detect the hardware again, we've updated to the latest Dell chipset drivers, we've tried every USB port on the back of the workstation (6 of them), the 2 USB ports on the front. The mouse works on none of them for longer than a few seconds.
The system does have a USB keyboard attached, and this works perfectly, but I haven't tried any other USB device, such as a flash drive, yet, so don't know if these would work!
Has anyone else come across this problem before? Anyone know how to resolve it?
