After reboot always problems with all usb sticks

Add-ons Bindings
1

Hi all,

every time after rebooting my raspberry pi I got big issues with all my usb sticks (see below with sticks with corresponding bindings installed). For the zwave stick, I use a Z-Wave Plus USB Stick (ZME_UZB1) stick, for the MaxCul I use a Busware CC1101, for the Lacrosse USB Stick I use a JeeLink usb stick.

The command: ls -l /dev/serial/by-id results in the following:

lrwxrwxrwx 1 root root 13 Mar 12 17:23 usb-0658_0200-if00 -> …/…/ttyACM0 this is the ZWave Stick
lrwxrwxrwx 1 root root 13 Mar 12 17:23 usb-busware.de_CUL868-if00 -> …/…/ttyACM1 this is a MaxCul
lrwxrwxrwx 1 root root 13 Mar 12 17:23 usb-FTDI_FT232R_USB_UART_AI03D96I-if00-port0 -> …/…/ttyUSB0 this is a JeeLink Lacrosse Stick

But all I got in the logfile this (as an example for ZWave):

2018-03-12 17:30:16.715 [INFO ] [ing.zwave.handler.ZWaveSerialHandler] - Stopped ZWave serial handler

2018-03-12 17:30:16.738 [INFO ] [ing.zwave.handler.ZWaveSerialHandler] - Connecting to serial port '/dev/ttyACM0'

2018-03-12 17:30:16.750 [INFO ] [ing.zwave.handler.ZWaveSerialHandler] - Serial port is initialized

2018-03-12 17:30:16.754 [INFO ] [mmandclass.ZWaveSecurityCommandClass] - Update networkKey

2018-03-12 17:30:16.758 [INFO ] [ve.internal.protocol.ZWaveController] - Starting ZWave controller

2018-03-12 17:30:16.762 [INFO ] [ve.internal.protocol.ZWaveController] - ZWave timeout is set to 5000ms. Soft reset is false.

The ZWave Stick is listed as Offline, as well the Lacrosse items are not updated anymore; MaxCul cannot send commands anymore to the thermostats, which results in the following entry in the logfile

2018-03-12 17:35:00.521 [ERROR] [ing.maxcul.internal.MaxCulMsgHandler] - Not enough credit after waiting. This is bad. Queued command is discarded

Can anyone help me with this?

no one a idea?

I have the same error message when I try to pair the first thermostat. Did you solve your problem?

4

yeah it is solved! use symlinks! this issue is caused by different usb locations after reboot, and symlinks will solve that.

5

Can you give me some more Information? How do i use it?

@volcore79 Here’s a guide with all the info.https://community.openhab.org/t/raspberry-pi-make-serial-usb-ports-persistent-via-symlinks/35847?u=h102 may need to adjust if not using RPI.

Thanks. Great documentation. But I am not able to use the new symlink in OH2. I unplugged every usb device but the MaxCul usb device and use /tty/ACM0 on the beginning. There is no error in openhab.log regarding CUL anymore. But I still see this message “Not enough credit after waiting. This is bad. Queued command is discarded” when I try to set the temperature…

same for me… problem exists since ever. at the moment i try to switch to the eqiva bluetooth radiators from eq3. hopefully, they are more easy in terms of maintenance and set up
