Without enabling uftdi debugging, the dmesg only notes device connections and removals (btw, the old usb stack would crash the system, if attached uftdi deviced was removed and the cuaU* was accessed, so, yes, there is an improvement ,)) Sep 9 15:49:46 sklepas kernel: ugen0.2: <Teltonika> at usbus0 Sep 9 15:49:46 sklepas kernel: uftdi0: <Teltonika ModemUSB/G10> on usbus0 Sep 9 15:56:08 sklepas
