USB Device mode communication problems

Added by iseori kang 9 days ago

USB0 is set to device mode.
It stops working on some laptops.
The driver is detected but communication stops.
The problem does not occur when connecting through a USB hub.
Have you ever seen a similar case?

Hello,

How is the USB0 device configured? As a gadget device (rndis, cdc, serial port, mass storage device, etc.)?

We have not seen this behavior here, I'd like to try to reproduce your setup if possible.

With regards,
Mike
