Remote solution to decrypt disk at boot (jlai.lu)

Hi there ! I have a little box at home, hosting some little services for personal use under freebsd with a full disk encryption (geli). I'm never at home and long power outage often occurs so I always need to come back home to type my passphrase to decrypt the disk.

I was searching this week a solution to do it remotely and found the "poor-guy-kvm" solutions turning a Raspberry like board (beaglebone black in my case) in a hid keyboard. It works fine once the computer has booted but once reboot when the passphrase is asked before it loads the loader menu, nothing. When I plug an ordinary USB keyboard I can type my passphrase so USB module is loaded.

Am I missing something ? Am I trying something impossible ?

(I could've asked on freebsd forum but... Have to suscribe, presentation, etc... Long journey)

Yes the beaglebone black is currently powered by USB. Unfortunately I am not able to debug the board while it's not working due to my lack of skill... I don't know how to do... Maybe I can read dmesg on the bbb for a message stating this nonworking state while it asks for passphrase on the PC for a first step... Yes once it's booted, freebsd see it as a single hid device, just a hid device
