I have a Proliant 1850R with Windows 2000 that in Device Manager | System
Devices shows a yellow error/exclamation next to:

Intel 82371AB/EB PCI to USB

The Internet is loaded with users with the same error across a large number
of different systems. One user reported that it was due to a failure to
associate the USB feature on the motherboard support with an IRQ.
Proliant 1850R doesn't have native USB support, but we did add an Adaptec
five port UBS 2.0 card. We ran the Compaq Proliant SmartStart utility,
which allocates motherboard resources for that PCI card. I checked in the
detailed BIOS setup screen that all of the PCI functions for that slot were
enabled. Should I be doing something more?

In Device Manager the Intel 82371AB/EB is still showing an error condition
under Windows 2000.

Attempts to insert just some models of DVD drive to that system give an
immediate blue screen of death as well, further suggesting that there may be
a USB driver problem, and the suddeness of the blue screen certainly seems
to agree with the idea that the system interrupts are not being handled
correctly by the driver. The drivers for the Adaptec card all seem to have
installed with no errors showing in Device Manager.

Any ideas on how to get USB working correctly on this server?
