I refurbished a 3 year old computer that has a VIA motherboard with VIA 
chipsets. It worked fine before I reloaded the OS and the drivers. Now 
the USB ports don't recognize flash drives (several different brands) in 
the USB ports. They show up in "My Computer" with a question mark, then 
after a short time they show the icon as available, then it goes away 
after a minute or so. The eject icon shows that the drive can be 
ejected. This happens on all 6 of the USB ports. The drivers are up to 
date, no further updates available. So I installed a PCI USB card that 
works ok. But I don't know why the internal USB ports are so flaky. The 
OS, Win XP Home is up to date.
