Need to update and close this issue - the problem is the protection diode on that board. In the new QT Py 2040, there is a jumper to short it - but with it in place, which is true on the M0 QT Py, the board will not power the USB device.
So, the QT Py M0 can't be used as a USB Host without removing that diode and shorting the connection.

Just an update, I have tried every conceivable combination of USB-C device & adapter including the adapter above, others that were not listed as USB 3.0, those that specifically said OTG as well as a direct USB-C Mouse (with no adapter).
The QT Py never gets beyond "Detached, waiting for device" and nothing ever enumerates.
Any guidance would be appreciated.

Good to know, I was going to use two QT Py actually for this reason. Then I stick with two Trinkets M0.
