Here is a strange problem:
First i've thought that it was because of Win2k's crappy drivers, then
upgraded to XP SP2 Pro but the same problem, if i connect flash drive
with my SD card reader (USB), the flash drive will not be recognized
any longer. But if i run it alone or other USB devices like USB
gamepad or 2 USB flash drive, it works OK. I also tried different
ports with no help, the other USB devices or this USB devices works
well with another system when connected together.

I've checked system info with no conflict, only there are some IRQ
sharings which haven't been problem since i plug card reader with
flash drive at the same time.

What should i do?

Please help

Thanks.
