The fido support needs a usbhid device, while the crypto stuff needs a
usbgen device. The device probably offers two interfaces, and we just
have to make sure to attach them separately (like we do e.g. for
JTAG/serial combos in uftdi).

With a kernel that makes it attach as usbgen, can you show the output
of usbgen from pkgsrc/sysutils/usbutil for your device? Like:

	usbgen -f ugen0 -v -D

That would probably help to find a patch that allows both modes at the
same time.
