I assume you already have the driver loaded on the FreeBSD side. The
Beaglebone side will be configured differently depending on whether you
use CDC or Remote NDIS; I'm fairly sure that it supports both, and
FreeBSD certainly does.

Sounds reasonable. Disabling umass entirely might be fairly difficult,
and is unlikely to be necessary.

It's possible that the Beaglebone emulates a umass device by default;
you can check this by trying to figure out what kind of filesystem the
FreeBSD machine sees, and maybe mounting that. If that works, then at
least part of the problem is that you haven't configured the Linux side
correctly, as opposed to the FreeBSD side.

Good luck.
