The udav
device driver first appeared in

The udav
driver was written by
Shingo WATANABE
<nabe@nabechan.org>
and ported to OpenBSD by Jonathan
Gray
<jsg@openbsd.org>.
RD9700 support by Takayoshi SASANO <uaa@uaa.org.uk>.
The RD9700 sometimes lacks zero-length packets to terminate USB transactions, which can cause USB IOERRORs.
