usb problem again

[badgolferman]

I have two USB 2.0 PCI cards installed in my computer now. One is
based upon the NEC chip and the other is based upon the VIA chip. My
motherboard is an older one that supports USB 1.1 for its own USB
connectors.

The problem is any device that makes itself a drive when connected
loses connection when accessed or file transfer begins. Cameras,
camcorders, flash drives, external drives all get write delay fail
errors or just vanish from the list of drives. Everything works fine
when connected to the motherboard's USB 1.1.

The NEC was my first add-on card and I just bought the VIA one hoping
it was the card. The generic Windows XP drivers are loaded. Device
Manager is perfectly happy with the installations. I have moved the
cards around to separate slots and used each one individually.

I can't afford a new motherboard/CPU/RAM etc. at this point and really
don't need an upgrade other than this confounded USB problem.

I think it's a Windows XP problem because _everything_ seems to work
with those NEC cards, and Microsoft issued a hot fix for write delay
errors in general:

but after I installed it and rebooted, the computer still reported
write delay errors. However chkdsk found no problems, before or
after.
