Thanks for the detailed feedback @dpgeorge I think I've got this in a better state now. I didn't realise just how much extra customisation had been added to the Arduino...

I actually have a micropython USB Host integration underway already based on the TinyUSB Host support. The initial pr on this will support CDC serial, MSC (mass storage) and HID....

It will probably need some more integration work to include it in esp32 port, particularly around the tinyusb config file. I was doing all my initial testing with rp2.

Thanks, yep the main known way to trigger it is to have truststore injected into the python environment before pip itself runs, as is done with the current versions of...

> I wasn't aware it was still relevant with truststore now available Yeah I'd thought it might fade out of use, however the point of difference has been for it...

> pip has adopted native truststore support: could pip-system-certs detect pip that supports truststore by default and not enable the patching? Yes that would have been preferable now, however the...

> special test file name prefixes/suffixes Yeah I do think it'd be helpful to have these itemised somewhere as it's certainly not abvious for new developers! I'm not too sure...
