Two ways to go on this one:

1) Use an FTDI serial console to jump into the firmware and re-enable
the USB

2) Use something like a SPI Hook or a Dediprog and blast the firmware
back down into the chip.  Mind, if you have a SPI Hook you also have an
FTDI serial device so you should try #1 first.

the MAX doesn't have this, but the Turbot, with a newer firmware does
have a jumper that can be used to restore the firmware settings back to

It was having some issues with the USB (it showed "set sel for device-initiated u1 failed"). I was debugging it and I was messing around with the firmware settings and I ended up disabling USB. Now, I cant get my usb disks working nor can I change settings on the firmware as keyboards are not working.
