Hi,
Could you try the HPS USB stack first?

Download the SVN version. You need FreeBSD 6.2.
What processor type are you using ?
It might be that the USB interrupt handler uses the wrong buffer size.
If it is the same, turn on debugging:
sysctl usb.ukdb.debug=15
I know that that the ukdb driver is called without Giant locked in the 
official USB stack, for example, which might lead to races.
--HPS
