Is your feature request related to a problem?

I'd like to add xbox controller support to the tuh. The xbox controllers are vendor specific and the vendor class driver seems broken: #2684

Describe the solution you'd like

Allowing to add custom class drivers to usbh_class_drivers[] in usbh.c would allow custom class drivers without the need to change/add anything to tinyusb. A simple solution may to allow the user to statically add an entry to this list via some #define in tusb_config.h

There's some discussion about this at #1929. But that approach would IMHO only work if the device would report as a hid class device which the xbox controllers don't.

There seem to be variants of tinyusb that implement something like this as this code snipped suggests:

I have checked existing issues, dicussion and documentation

You've been able to hook in your own USB host drivers since #2222

I made this a while ago but I try keep it up to date you https://github.com/Ryzee119/tusb_xinput
