If you look into dmesg after enabling the dyndeb messages, you should see much more than USB connect messages. But be aware that there are quite a lot of messages that appear in dmesg. Best is to enable the dyndbg, then immediately plug in the device, and after a few seconds (5 seconds or so) you should do a dmesg > mylog.txt Then you have the dmesg captured into the text file mylog.txt and you have time to check it. Check for USB error messages in this file. Best regards Carsten
