These seem to be the bane of a lot of people's lives given the number of reports of them around the 'net, but I've not found any definitive resource on likely causes. I've been getting them since I did a clean install of Windows XP with SP2 on Monday (I was previously using SP1 and it wasn't broke so I didn't fix it).
I've applied the latest motherboard driver updates from Intel, applied a related hotfix from Microsoft, tested across multiple devices (HDDs and pen drives) and multiple ports, and still the error persists. I don't have any performance tweaks that commonly cause them applied, but I do have an ATI AGP card, which also seems to be a common cause.
Motherboard is Asus P4P800 (yup, nearly four years old, but again, if it ain't broke...)
I do have a spare USB 2.0 card I could install, but I'd rather eliminate other possible causes first.
Any ideas?
