I remember that, but I wonder why it works okay on x86. Hmmm... now that I check it again, it seems it only works on x86 if the ko is specified to be loaded in loader.conf (even if ugen is compiled out and not loaded). Loading it later after boot makes the uftdi_match fail. So that explains why it doesn't work on arm (no loader support for loading .ko's) at all. Ah... it also works if it's loaded at boot, unloaded later, then reloaded.
