They get interpreted as linux ioctl, as they are handled by the =20
linuxulator. You could try to write a wrapper there...

As long as you can specify the devices in the linux app, it's enough =20
to translate the ioctl's. Apart from that, there's some kind of =20
translation layer for devices already, but I don't know if it just a =20
Linux major/minor -> FreeBSD dev mapping, or if you can map linux dev =20
-> FreeBSD dev.
AFAIR HPS' USB stack has linux compatibility, maybe you should ask him =20
/ have a look at it.
Bye,
Alexander.
