USB Powered Speakers

[Programmer In Training]

I have acquired a pair of Compaq USB /powered/ speakers. On my parents
XP machine they don't seem to cause any problems, but when I hook it up
to listen on my FreeBSD box I have absolutely nothing but problems with
the speakers (even when turned off but still plugged in) interrupting
the normal operation of my keyboard (basically it seems that power is
cut to my keyboard at random). I have a beefy power supply (650W) so I
really shouldn't be having any power distribution issues.

I've tried the speakers in both the on-board USB ports and the USB
expansion card (PCI) with the same results.

Any ideas?
