Scott Shawcroft	1629faf8b3	Make usb_host.Port a singleton ... This allows you to initialize usb_host.Port once successfully and then returns the same object as long as you pass the same arguments in. It does allow you to fix incorrect pins but not switching from one valid set to another. (It needs a reset for that.) This also moves hcd cache operations to RAM so that they don't access the cache when doing maintenance.	2023-07-18 10:40:54 -07:00
Scott Shawcroft	83593a1558	Start of USB host API ... This allows you to list and explore connected USB devices. It only stubs out the methods to communicate to endpoints. That will come in a follow up once TinyUSB has it. (It's in progress.) Related to #5986	2022-03-07 18:07:25 -08:00
