Thanks for the constant update. I've spotted a couple more things to fix before merging.

Remove prints from within the library. Folks using the library won't care about them.

Don't catch all Exceptions. You'll get reloads and such too. You probably just want USBError.

This is one of two library changes (Adafruit_USB_Host_Descriptors and Adafruit_CircuitPython_USB_Host_Mouse) that provides a framework to support combination keyboard/trackpad USB devices. A PR adafruit/Adafruit_Learning_System_Guides#3169 to the Fruit Jam PyPaint application has also been submitted which shows the use of these changes from an application perspective
This change generalizes the _find_boot_endpoint so it can locate boot or non-boot (report) endpoints. These changes are backwards compatible as the original public helper functions names haven't been changed and perform the original functions. There is a new helper function
find_report_mouse_endpointwhich an application can call (if no boot mice are found for example) to locate non-boot HID devices.
