I am also having problems with USB3 hub. When plugging a hub in the USB3 top port, the journal log is filled with usb usb6-port1: Cannot enable. Maybe the USB cable is bad? lsusb -t gives: /: Bus 001.Port 001: Dev 001, Class=root_hub, Driver=xhci-hcd/1p, 480M /: Bus 002.Port 001: Dev 001, Class=root_hub, Driver=ehci-platform/1p, 480M |__ Port 001: Dev 002, If 0, Class=Hub, Driver=hub/4p, 480M |__ Port 004: Dev 003, If 0, Class=Hub, Driver=hub/4p, 480M /: Bus 003.Port 001: Dev 001, Class=root_hub, Driver=ehci-platform/1p, 480M /: Bus 004.Port 001: Dev 001, Class=root_hub, Driver=ohci-platform/1p, 12M |__ Port 001: Dev 003, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M /: Bus 005.Port 001: Dev 001, Class=root_hub, Driver=ohci-platform/1p, 12M /: Bus 006.Port 001: Dev 001, Class=root_hub, Driver=xhci-hcd/1p, 5000M Plugging a USB3 drives without a hub works correctly. Everything works fine with legacy kernel.

Thank you very much for the hard work! I've spent the whole evening trying various combinations of kernels and dtbs. Unfortunately, I was not able to have that USB3 hub working (except for legacy 5.10). With 6.2 kernel and usb-c dtb, it shows as USB2 only. What is strange is that I'm sure I had it working in the past, with a 6.2 kernel. Plugging a single device in the USB3 port works. Plugging the hub on another machine works. Using 5.10 kernel works. Plugging the hub with 6.2 or 6.6 kernel on either USB3 or USB-C does not work. If anyone is willing to help me debug this, it would be very welcomed. I'm not sure what I should try to go further.

Hello @balbes150, Sorry to insist, I'm still looking for a working 6.x kernel with wireguard and usb3 (or usb-c). I'm willing to try compiling the module by myself, but I'm not sure what repository to use. Could you share your building process? Best regards
