How to implement USB host class driver that supports many vid/pid pairs?

[Till Harbaum]

I've implemented a USB host class driver for xbox controllers here:
https://github.com/harbaum/CherryUSB/tree/master/class/xbox

This needs support for a long list of vid/pid pairs like e.g.
https://github.com/harbaum/CherryUSB/blob/master/class/xbox/usbh_xbox.c#L111-L215

To achieve this I have changed the single vid/pid entry to point to an array of entries like so:
https://github.com/harbaum/CherryUSB/blob/master/core/usbh_core.h#L63

This is imcompatible with upstream cherryusb.

How do I properly implement a driver that supports multiple vid/pid pairs in cherryusb?

I've just updated my port to the latest bouffalolab_sdk and the cherryusb 1.2,0. Feel free to re-use any part you want.

I've also updated https://github.com/harbaum/bouffalo_sdk/blob/master/drivers/lhal/src/bflb_usb_v2.c for the latest cherryusb 1.2.0

Thank you sir, i have reviewed your code, and give you a few suggestions:

• in usbh_find_class_driver , if any flag does not match, please continue instead of going on next.
• some changes in vendor do not modify
• change USB_CLASS_MATCH_DEVICE_LIST with USB_CLASS_MATCH_ID
• format your code.

And after doing all, you can create a pr, sincerely wait and thank you for your pr.
