Not that it matters a lot anymore for those units however the USB ID
is allocated for multiple different units, this patch will break some
of them.
If you want to use that use the unit with this driver you're on your
own and have to assign it via sysfs and usb/bind.
It was a joint project many years ago before we also started to design
and manufacture our own units.
