The problem was something to do with "data toggles" in the EHCI code - see
http://cvsweb.netbsd.org (I think), look in src/sys/dev/usb/ehci.c and it
was fixed a couple of months ago (by Matthias Drochner)
more than one person was seeing the exact same thing - the first packet
sent on the control endpoint (a command) would generate data on the
interrupt endpoint (an event) but the second would not, and thus the
'dongle did not respond' error sounds familiar..
I don't know if the same problem exists on FreeBSD (it was the same USB
stack though has had different fixes applied over time), and IIRC the
FreeBSD ng_ubt driver handles the USB interrupt transfers slightly
differently, so it could be unrelated, but its worth a try..
