iMX8QM FUSB302 Type-C Initialization Issue

Hi,

We are working on iMX8QM custom board with 4.14.78 Kernel BSP release, in which we are using "FUSB302" Kernel driver for USB 3.0 Type-C detection.

The USB Type-C devices detecting as 3.0 (Super Speed) during the hot plug, but during kernel boot the same is detecting as 2.0 (High Speed).

Detection during boot time:
usb 1-1: new high-speed USB device number 2 using cdns-usb3
Detection during hot plug:
usb 1-1: new SuperSpeed USB device number 2 using cdns-usb3

Is the same issue observed in iMX8QM reference board?
Kindly suggest the solution as soon as possible.

Best Regards,

Prashanth Kumar K

Hello,

Unfortunately, we are not able to assist you, since the i.MX8QM is still on preproduction and we do not have a way to test your problem. I apologize for the inconveniences this could give you.

Best regards,

Diego.
