  1. Update: Ich habe die Webcam nun noch via ein USB Hub angeschlossen. Wenn ich via ssh versuche den solid-state-switch zu schalten mittels Python (nicht brickv) dann erhalte ich diesen Fehler: Traceback (most recent call last): File "solidState_OFF.py", line 20, in <module> print ssr.get_state() File "/usr/local/lib/python2.7/dist-packages/tinkerforge/bricklet_solid_state_relay.py", line 72, in get_state return self.ipcon.send_request(self, BrickletSolidStateRelay.FUNCTION_GET_STATE, (), '', '!')

  2. Es hat einen quad-core iMX6 Prozessor, ohne WLAN. Weil das Udoo Board zuwenig USB Strom liefern kann ist die 5V USB Versorgung gestützt mit einer extra 5V 2.5A Stromversorgung.
  3. Hallo, ich habe ein Udoo Board it Debian 8.9 mit einem Master mit 4 bricks, und noch eine USB Webcam am Udoo angeschlossen. Nach einem Neustart funktioniert brickv und ich kann die Bricks ansteuern, aber dann nie mehr. Es müsste ein USB Problem sein gemäss logfile: cat /var/log/brickd.log: 2017-12-03 11:57:22.878542 <I> <main_linux.c:450> Brick Daemon 2.3.1 stopped 2017-12-03 11:57:22.949180 <I> <main_linux.c:284> Brick Daemon 2.3.1 started (pid: 4525, daemonized: 1) 2017-12-03 11:57:22.973448 <E> <usb.c:675> Could not get product string descriptor for USB device (bus: 2, device: 6): LIBUSB_ERROR_PIPE (-9) 2017-12-03 11:57:22.981803 <W> <usb.c:181> Ignoring USB device (bus: 2, device: 6) due to an error lsusb: Bus 002 Device 004: ID 148f:5370 Ralink Technology, Corp.

Ich vermute ein USB Konflikt, ev. mit der Logitech Webcam. Kann mir jemand weiterhelfen? Merci, Rudi
