Comparing them might = show where the problem is. In addition, before plugging in the device you should enable USB dynamic debugging by doing: echo 'module usbcore =3Dp' >/sys/kernel/debug/dynamic_debug/control and then afterwards attach the relevant parts of the dmesg logs. --=20 You may reply to this email to add a comment.
