Hi,=20 after connecting this QR reader I see a new /dev/ttyU but as soon as I = try tip, the device disconnects. (BTW, it=E2=80=99s configured as a =E2=80=98Virtua= l Serial Port=E2=80=99) dmsg: =E2=80=A6 Jan 2 10:54:57 pampero kernel: umodem0 on uhub1 Jan 2 10:54:57 pampero kernel: umodem0: <SM SM-2D PRODUCT USB UART, = class 2/0, rev 1.10/1.00, addr 38> on usbus0 Jan 2 10:54:57 pampero kernel: umodem0: data interface 1, has no CM = over data, has no break Jan 2 10:56:01 pampero kernel: umodem0: at uhub1, port 2, addr 38 = (disconnected) Jan 2 10:56:02 pampero kernel: umodem0:=20 Jan 2 10:56:02 pampero kernel: detached Jan 2 10:56:03 pampero kernel: umodem0 on uhub1 Jan 2 10:56:03 pampero kernel: umodem0: <SM SM-2D PRODUCT USB UART, = class 2/0, rev 1.10/1.00, addr 38> on usbus0 Jan 2 10:56:03 pampero kernel: umodem0: data interface 1, has no CM = over data, has no break =E2=80=A6 and usbconfig: pampero# usbconfig ugen0.1: <0x8086 XHCI root HUB> at usbus0, cfg=3D0 md=3DHOST spd=3DSUPER = (5.0Gbps) pwr=3DSAVE (0mA) ugen0.2: <GenesysLogic USB2.0 Hub> at usbus0, cfg=3D0 md=3DHOST spd=3DHIGH= (480Mbps) pwr=3DSAVE (500mA) ugen0.4: <Logitech USB Receiver> at usbus0, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DON (98mA) ugen0.5: <Prolific Technology Inc.
