What is the AT command to change the USB speed?

IoT Modules MC/EM Series

In the EM/MC series, the latest firmware shows that there is now an AT command to change the USB speed. I have looked at the latest available AT command doc and do not see it. Does anyone know what it is?

SWI9X30C_02.29.05.0 - Add AT Command to force USB speed. QTI9X30-2463.

Thanks.

Wild guess:

at!usbspeed?
SUPPORTED:Super-Speed
CURRENT  :High-Speed

OK
at!usbspeed=?
!USBSPEED: <max_supported_speed>
<max_supported_speed>:
  0 - High Speed
  1 - Super Speed

OK
