Why does my Filco keep dropping it's USB connection

[a_fluffy_kitten]

So today is the first day I've had a chance to really use the Filco since receiving it mid-week.  (I'm using it to butcher some MATLAB code, fwiw.)  Every five minutes or so the keyboard stops working for a few seconds, and then windows plays the standard "beedoop" sound indicating a USB device has been removed from the system, and then a few seconds later the keyboard magically starts working again.

Has anyone ever seen anything like this before?  (Insert beeboop sound here, wait for keyboard to start responding again.)  Any ideas what might be causing it?

I've already tried the two things that usually fix problems in Windows:

1) Restart Windows.
2) Unplug they keyboard and plug it back in.

Thanks for the advice guys.  I tested it on Mrs. a_fluffy_kitten's computer and it is doing the same thing.  ripster you called it - it's RMA time.  :/

Just looking at your sig, is this the second Filco you've have die on you?

No - this is my first Filco and it got here Wednesday.  The second was ordered yesterday morning and isn't expected to get here until next Thursday.
