  "message": "Add extra hub_port_reset for MTK USB virtual hub\n\nMTK\u0027s USB virtual hub is at a wrong state after a software reset. Thus\nhub_port_init times out while waiting for the descriptor, causing a \u003e4s\ndelay per TPU engine initialization. Adding an extra hub_port_reset seems\nto put the hub back to the correct state, and cuts the response time to\n\u003c1s to get the descriptor after the reset.\n\nChange-Id: If1e17fe2a71f49784ee0b9e8fc0b16f7d06753ec\n",
