Hi,
it comes up in ifconfig:
cdce0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
lladdr MA:CA:DD:RE:SS
index 27 priority 0 llprio 3
I assume, it would "just work" TM (c), but it switches to the mass storage rally quick, so I can't test my theory.
I can eject the cd using "doas eject cd0", however it stucks in cd mode after this command, so while it really stops the switching back-and-forth it doesn't makes the hw usable :(

If i connect it, it shows up as cdce, but then it automatically detaches and comes up as a usb storage device (it holds the the windows driver ). It does this repeatedly. Can I force somehow OpenBSD to ignore the mass storage device? DMESG below:
