i.MX RT Two USB Devices

On the i.MX RT1062 we need the two USB ports to work as device ports simultaneously with detach detection on both.

 

Errata ERR010661 states that this is not possible due to VBUS leakage causing a single port detach to not be detected.

 

If our custom hardware, external to the processor, detects the presence of VBUS on each USB port and sends two signals to two GPIOs on the RT1062, could we then work around this issue in software?
