General USB Question

[Guest]

I recently had several Dell Optiplex GX270 and 280's crash each time a usb
device was connected. I have ruled out malware etc. I uninstalled all patches
from the last month. I even uninstalled most of the software on the system.

If I uninstall all USB controllers from the device manager they are
renumerated. However, if I plug a mouse into one port and it prompts for
drivers which I install and then move the mouse to another port it prompts
again for drivers. Before this problem you could move the mouse between ports
and it didn't promt for drivers.

I am using the mouse as an example. All USB devices act the same way. Dell
hasn't had a chipset update since the original release. There has been a BOIS
update but this didn't solve the problem.

The only drivers that I know of that have been possibly updated were the NIC
driver. I have removed all instances of NIC drivers and even removed the OEM
drivers. Still the same behavior.

I have tried rebuilding the WMI repository and this amounted to the same
effect as renumerating the USB in device manager.

I have removed the ability for the OS to disble the device to save power and
this doesn't solve the issue.

If I prevent Xp from rebooting the error seen is 0x0000007e (0xc0000005,
0x00ee10e0, 0xf8bd57f8, 0xf8bd54f4)

What I am lacking is an understanding of how to interpret the above error to
see what it is referencing. Also, I am wondering if there is something
further I could do to fix the problem. Any ideas?
