Your device seems to hang when asked for this descriptor, so don't ask it a= nd see what happens. I tried it on my own 5Gbps UVC device and it still works, though many other things break without BOS and hence the patch checks for vendor ID. You will need to edit it with the ID of your device. The patch a= lso prints IDs of new devices to a) confirm that the earlier device descriptor request was successful and b) help with adjusting the patch if 10Gbps vendo= r ID is different from 5Gbps vendor ID. It should now look like this: [89023.940009] usb 19-2.3: new SuperSpeed USB device number 8 using xhci_hcd [89023.954100] usb 19-2.3: new device idVendor ac8 idProduct 3420 [89023.954115] usb 19-2.3: too lazy to get BOS descriptor or descriptor too short --=20 You may reply to this email to add a comment.
