Or make uhid not attach at all on FIDO devices and instead use ugen from
userland?

Or solve the long standing "every usb devices should be able to eject
its driver and be used as ugen instead" problem, see also the various
JTAG devices showing up as dual uftdi and you need to override in your
kernel config like:

# GuruPlug JTAG debug interface
ugenif* at uhub? vendor 0x9e88 product 0x9e8f interface 0 flags 1


Most devices go via uhid to make userland access easy on windows, but for us
it makes no real difference.
