Thanks for the links, but most of this is either about freebsd or Linux, which isn't really applicable in my case. AFAIK there is no camcontrol command in openbsd.
I can try to compile usbmodeswitch on OpenBSD, but I never had good experience with it.

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:
