A friend of mine, Kitty has a flash drive of 512MB, such a small size of capacity should be recognized even in win98.
She wanted some MP3 songs and so I took her Flash Drive home.
It's weird that when I plugged it to my notebook, the power light was 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 changed to another USB port and tried, but it failed to work neither.
I had 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 the USB port of my Desktop should not be enough; but any of these USB ports had been tested with a USB HDD of 80GB, so the reason why the USB port can drive a USB HDD but fails to drive a 512MB Flash Drive is a mystery to me!
any idea?
