[Feature]Add PICO PIO USB support

[sfranzyshen]

Add support for https://github.com/sekigon-gonnoc/Pico-PIO-USB

with the latest pull request to Pico-PIO-USB ... TinyUSB support has been added
sekigon-gonnoc/Pico-PIO-USB#22

and there is a active pull request to TinyUSB itself ...
hathach/tinyusb#1412

Ref.

#168

[hathach]

we will add host support to this library, but there is always some lag between this arduino library and tinyusb upstream. Please be patient

[kilograham]

can you please hold off on this; i would like to back-out and fix up the way the PIO support is integrated into the build. It will likely break whatever you do here.

[kilograham]

I added a PR hathach/tinyusb#1467

[sfranzyshen]

It looks like pull-request #173 and release 1.11.0 handled this?

[hathach]

no, it is an weekly scheduled release probably by script on all adafruit repo. and only update tinyusb core only.

[hathach]

implemented by #175

Just curious, is there something that makes implementing the host API easier with PIO USB than with normal USB?

I don't think so. The appeal of using PIO is having the USB device active at the same time.

Hmm okay, well I hope it's planned to have host support with the built-in USB controller as well 🙏
I've been hoping to move to this library for an existing device I designed, which uses the actual USB controller for USB host, and I use the PIO for other comms so wouldn't be able to use PIO USB anyway.
