J120 USB not recognized with JetPack 4.3 on TX2

Hi,

USB is not recognized with JetPack 4.3 on TX2 ( even mouse and keyboard )
AUVidea has instruction on only JetPack 4.2.

Is there anyone who can let me know how to patch J120 USB driver?
Pls help this poor newbie on TX2 ^^;

Complain to Auvidea. They should release a patched JetPack 4.3
