I am just curious.
What manufacture / model and GB size of USB stick are you using?
When you plug the USB stick into a FreeBSD system what version of the 
USB standard is used in the firmware on the USB stick (1.0, 2.0 or 2.2)?
The firmware USB version standard used by the stick is displayed when 
the stick is first plugged into a Freebsd release 7.2
