Hi Peter

Thanks for getting back to me so soon.  Apologies if I've misinterpreted 
your advice, I've only been using DesktopBSD for a week.

Anyway, after enabling debugging lots of messages similar to the one 
below appeared in the log after inserting a stick:

And rebuilding the kernel to use atausb instead of umass resulted in no 
improvement.  I inserted a stick as soon as I had rebooted with the new 
kernel and dmesg | tail showed the following:

afd0: FAILURE - PREVENT_ALLOW ILLEGAL REQUEST asc=0x24 ascq=0x00
afd0: FAILURE - PREVENT_ALLOW ILLEGAL REQUEST asc=0x24 ascq=0x00
afd0: FAILURE - PREVENT_ALLOW ILLEGAL REQUEST asc=0x24 ascq=0x00


And this was in the logs:

The usb sticks I'm using are two corsair flash voyagers 4GB (16mb/s) and 
one generic 2GB stick (12mb/s).

I'm not sure what you mean when you say there is a way to nice/throttle 
USB transfers now.  How would I do that?

Hope this means more to you than me, and thanks again.
