ESP32-S2

Is your feature request related to a problem?

I'm making a gaming mouse using an ESP32-S2-DevKitM-1U. Modern gaming mice all report at 1000hz with 16 bits of motion per frame.

The HID USB mouse implementation only support 8 bits of motion data per frame: https://github.com/espressif/arduino-esp32/blob/master/libraries/USB/src/USBHIDMouse.cpp

At 125hz and 800dpi, this limits the max tracking speed to 0.5 meters per second. At 1000hz, it's 4 meters per second, which sounds like a lot, but isn't enough for game genres that involve very fast flicking. At higher DPIs, the max tracking speed is reduced; 800dpi isn't really enough to run a HiDPI monitor any more, so "silly" DPIs like 1600, 3200, etc. are increasingly common.

TinyUSB doesn't seem to have a report type for 16-bit mice out of the box, but someone seems to have gotten it working anyway: hathach/tinyusb#366

Describe the solution you'd like

Add a second class that uses 16-bit motion deltas and a proper report descriptor.

Describe alternatives you've considered

Overclocking above 1000hz (e.g. to 8000hz) only works on "High-Speed" USB devices, not "Full-Speed" as is usually used for keyboards and mice.
