Hi all I have a system, using a Xilinx ZynqMP with kernel 4.19, using the build in dwc3 core as a USB device. (It is a custom device using ConfigFS / FunctionFS). In a certain scenario I would like to force the dwc3 to only connect via superspeed and not fall back to USB2. What options exist for forcing the dwc3 to keep retry? I know about the U2RSTECN from GCTL - https://www.xilinx.com/html_docs/registers/ug1087/usb3_xhci___gctl.html So was wondering if other options existed, where I can force it to continue try to connect as SuperSpeed. Or if it is possible to setup the high speed descriptors for ffs, so the host automatically will reset the bus / device so it newer will be reported as connected, unless it is with super speed. Thanks ahead. Claus Stovgaard
