Hi Walter, i had a similar issue with a different device. Please check, if you have dynamic debug enabled in your kernel (/sys/kernel/debug/dynamic_debug/control exists) Then you can enable additional kernel messages using echo -n 'module xhci_hcd =p' > /sys/kernel/debug/dynamic_debug/control echo -n 'module usbcore =p' > /sys/kernel/debug/dynamic_debug/control Check which usb related messages you can enable through the dynamic_debug. (doing a "cat /sys/kernel/debug/dynamic_debug/control | grep usb" helps much) Finally, a fine resource is https://www.kernel.org/doc/html/v4.11/admin-guide/dynamic-debug-howto.html Best regards Carsten > -----Ursprüngliche Nachricht----- > Von: linux-usb-owner@xxxxxxxxxxxxxxx [mailto:linux-usb- > owner@xxxxxxxxxxxxxxx] Im Auftrag von walter harms > Gesendet: Mittwoch, 21.
