UpSquared failed to go super speed in device mode
I am facing an issue with the USB 3.0 OTG port of my Up2 board.
In host mode, using the USB3.0 OTG cable (OPT-UP-CABLE-USB-001), every thing works fine. USB 3.0 Devices are detected in SuperSpeed.
But in device mode, when I use a USB 3.0 Type-A to Micro-B cable, the Up2 fails to link in SuperSpeed and reverts to hi-speed. I have tried many kernels up to vanilla 4.18, multiple cables and multiples host computers (running linux or windows), without any improvements.
The UEFI firmware has been updated to the latest version and the DWC3 IP seems to be version 2.6.
I choosed this particular board because my project mandatory requires USB 3.0 device mode support. This seems to be a recurrent issue on other boards. Is there a known solution ?
Thanks for your help
