USB memory stick

[FloW]

Hi guys

First of all - I've been following the DragonflyBSD project now for 
quite some time via the 'stable' preview tags and it is probably the 
most innovative OSS project in the operating system world. Go on!

Now to my problem - I recently bought a USB memory stick, and it works 
with both Windows and FreeBSD. When I boot DragonflyBSD the error 
messages are something like:

uhub4: 1 port with 0 removable, self powered
uhub4: cannot open interrupt pipe
device_probe_and_attach: uhub4 attach returned 6
surrounded by lots of stray interrupt messages like:

sched_ithd: stray interrupt 7

The MB is based on NForce3 chipset (which is buggy, I know) and the 
memory stick is a Corsair Flash Voyager 4GB. I've tried both ehci in 
kernel and as a module - no go. Any ideas?

Regards

FloW
