I've not used the original Memtest86 in years, so the following may not 
apply if that's what you're using.

We frequently use Memtest86+ that is on the Ubuntu install CD at Free 
Geek Columbus.  The current Ubuntu 10.04 has version 4.00 included.  I 
don't remember anyone reporting your problem or anything similar.  I 
haven't looked at the Memtest86+ code in several years, but IIRC no USB 
kernel drivers are included.

I just booted one of my systems with the 10.04 CD, started Memtest86+ 
and inserted then removed a USB flash drive.  Mentest seemed to ignore 
this activity, so this suggests you have a local hardware issue. 
Assuming you're using Memtest86+ of course.
