Hi Henry.

After about a minute of running: usbhidctl -alrv -f /dev/uhid0 > dump, I get:

There is an option in the BIOS that allows me to disable BIOS support
for USB. I'll reboot and report back on whether or not it makes a
difference.

As with usbhidaction, I'm assuming I would need to be able to get
output from /dev/uhid0 in order to write a configuration file.
Correct?
