This attempts to fix a problem where a Fruit Jam board crashes if you access the CIRCUITPY drive while it's rapidly polling a gamepad using usb.core.Device.read(). The fix is incomplete.

I don't want to do this. It is TinyUSB's job to ensure it is in a good state to handle a read() call.

code.pyis rapidly polling a gamepad usingusb.core.Device.read(). For details on the problem seeThis fix is only marginally effective. It's still kinda crashy, but marginally less so than without the changes. I'm posting this here so people can poke at the code or try the CI build if they want.
