are devices like the max3421e and ch372 (& 376 which does host and some automatic stuff) outside of the scope of this project?

[ohsix]

and if not, which driver is the simplest or most straightforward for someone not super familiar with usb to try and implement support for them

thanks!

no, why would it is outside of this project scope though ?

[ohsix]

just thought it be better to ask

some aspects of the ch372 implementation happen automatically and i was unsureif every device had to work like native usb ip or if the high level usb uart/spi interfaces can usefully map to it (ch376 is the ch372 "plus", can do host mode w/ full control of the endpoints or MSC/HID/some other stuff by itself)

also i was looking in completely the wrong place to find an example driver, whoops

host/hcd.h & dcd_template.c was what i was looking for

thanks!

to be honest, I don't know much of ch372,though there is an PR to add support for another WCH here #1405 . As long as it is software controllable, I would try to support it if there is enough time for the work.
