That's a CH341 adapter.=C2=A0 I have a driver which should work.= =C2=A0 You can fetch an
updated usb/serial command from http://www.hamnavoe.com/usbser= ial (use hget).
If you want to build from source, updates to /sys/src/cmd/usb/serial are in=
http://www.hamnavoe.com/serial.tar

I would put a patch on sources but the Bell Labs server is unresponsive
at present.
