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
