Solve : flash drive can work in my Notebook but desktop?

1.	Solve : flash drive can work in my Notebook but desktop?
Answer» I have a flash drive of 128MB, such a small size of capacity should be recognized even in win98. It's weird that when I plugged it to my notebook, the power light is on and I can read and write the data, but when I plugged it to my desktop (XP SP2), the power light never turns on. I thought it may be the USB problem, so I change another USB port and tried, but it fails to work neither. I have tested those USB ports in my Desktop with other USB hardware, and they all works. So, come to the conclusion, I think the power assigned to any of the USB ports of my Desktop should not be enough; but any of these USB ports have been tested with USB HDD of 80GB, so the reason why the USB port can drive USB HDD but fails to drive a 128MB Flash Drive is a MYSTERY to me! Please advise!Have you tried this flash drive on any other desktops ? ? Quote Have you tried this flash drive on any other desktops ? ?
