Can you add an example about ch559 USB host? This is a very important feature thx

Thank you

I have not found a good framework for USB host. But you generally can copy example from WCH directly because you don't need interrupts for host.

what about to port this project to Arduino? https://github.com/atc1441/CH559sdccUSBHost

@relaxibus That is a working example, not a framework. You can not modify the code unless you are an expert in USB. But you won't need that code if you are an expert.
