OK. I missed that. Thanks.  Now rebuilding... but will take some while.

I will be back with the hw.usb2.umass.debug and hw.usb2.axe.dubug set, too.

It's called 'Low enegy profile FA PC: SFC-A016(L)' from
Interface Corp., but, there're only Japanese pages at the
moment.  Probably you can get some idea though:
http://www.interface.co.jp/sfc/sfc_spec.asp

They started making English pages but it is still quite empty:
https://www5.interface-world.com/

FWIW, it has a mini AB connecter, aside from the normal A
connectors, and they say that they have an USB client-side
driver for it on Windows XP embeded.  Can we make use of
this part of the hardware on FreeBSD as well?
