#6 - USB drive support #33

Closed vintagepc closed 3 years ago

Description

Adds support for STM32 USB OTG HS.

Have you tested the changes?

As far as I can tell, it is working - Mini404 can read a USB flash drive and start prints from it.

Other

Works with simulated USB storage and an image file. Host USB support will be left to a future task, if done at all.

Note - DMA is not supported/implemented, that will need to be done when/if it is turned on in the firmware.
