I patched your drivers/libhid.c and recompiled, which atleast allowed 
the incorrect code to be recognised as 'UPS'. Obviously, not enough to 
get things working...

Can't figure out how to do this and, in the light of Chris's comments

I recompiled my FreeBSD kernel without uhid.ko and can succesfully 
load/unload uhid as a module now.
