I would avoid the beaglebone for now, it has a hot plus usb issue that doesnt seem to be fixed even in some of the beta kernels.. anyhow just my 2 cents since I tried to get one working and just gave up.
It's running
fine for me on the 5-14 Debian firmware. Are you running an Angstrom release?
Edit: Reading comprehension - hotplug. I tend to power-cycle to reboot miners so I forgot that the habanero must be plugged from bootup.
