I have an Nforce2 motherboard, and I can't say I ever had any problems
with USB interfaces.
There is a motherboard manual here. JUSBV1 and JUSBV2 are 1x3 pin headers
with a jumper plug on each. The header controls how the USB ports are powered.
JUSBV1 controls the power choice for the rear (I/O area) two USB jacks. JUSBV2
is for the 2x5 USB headers, which would normally be cabled to a front panel USB
if one was present. I've seen a couple different pictures of your motherboard,
one with USB 2x5 headers installed, and another where there are no USB 2x5
headers installed. So I can't be sure that is what is wired to your front
panel. You say you have a USB card, so some of those have one or
two interfaces suitable for connecting to front panel USB as well.

There are two choices for JUSBV1/JUSBV2. They can be set to +5V or
+5VSB. The latter choice would be useful for a USB keyboard, where
you wanted the "wake up" function to work from the keyboard. If
you're not waking the computer from a particular USB interface,
then the +5V choice might be better for operation. On my current
computer, all the USB ports run from +5V. +5V is a stronger power
supply rail.
Your Biostar board does appear to have taken precautions for the USB
interfaces (like my Nforce2 board did). There is an electrolytic cap
next to the USB ports, to filter the power fed to the USB interface.
That is supposed to reduce the impact on system power, when a USB
device is plugged in. So it probably isn't a problem like that.
I'm suggesting +5V as a power source, more as a test case, than
as a sure-fire cure.
I doubt it is the USB Mass Storage class driver that is screwing up.
What are the odds of that happening ? Especially when the rear port
works OK with your Kingston 128MB.
Do you see anything in Event Viewer, in terms of any error message
logged during the jam-up ? Have you ever got a blue screen from
it, with an error number or message ?
