You should try enabling the options in:
- Startup>Boot>Boot device List F12 Option (most important)
- Config>USB (may be only for charging, but may also help)
- Security>I/O Port Access>USB Port (may be only for keyboard/mouse, but not clear)
and disable:
- Startup>Boot>Boot Order Lock (imporrant)
then Restart>Exit Saving Changes and press F12 furiously during next boot (as i don't know when exactly) and select USB.
