[nRF52840] USB HID communication

From the nRF52840, USBD — Universal serial bus device:
"The USB device (USBD) controller implements a full speed USB device".

In other words, the USBD of the nRF52840 does not support high speed mode.

I do not know of any HID transmission rate tests we have for HID.
But from the nRF52840, USBD — Universal serial bus device:
"Full-speed (12 Mbps) "
And from Appplication Note, nAN22 - Generic data transfer using USB HID:
"Maximum theoretical data transfer rate of 64 kB/s."

HI ：

At sdk15.3 Which is the HID routine?

Does the HID of nrf52840 support high-speed mode? Have you measured the transmission rate of HID?
