Hi, everybody.
I have a i.mx6 custom board and want to use the usb otg as host.
The board was designed by sabreAI board.
The otg id pin is grounded.
When boot the board by plug the mouse in the otg port, the below messages appear.
usb 1-1: new full speed USB device number 3 using fsl-ehci
usb 1-1: device descriptor read/64, error -71

usb 1-1: device not accepting address 5, error -71
hub 1-0:1.0: unable to enumerate USB device on port 1
