75XX USB Host

From Technologic Systems Manuals

The Cavium CPU supplies standard USB 2.0 ports. The power to the USB can also be toggled by setting a DIO.

# This is sourced in the initrd, but if you are running
# from Debian you will need to source the subroutine file.
source /initrd/ts7500.subr

# Power off USB
setdiopin 7 0

# Power on USB
setdiopin 7 1
