Error: Cannot Access /dev/ttyusb0
Just upgraded from snapshot to beta/RC. Edit: the same in ReleaseThe port in question still present in /etc/default/openhab2openhab is a member of dialout groupport is present:root@zbox:# ll /dev/ttyUSB0crw-rw- 1 root dialout 188, 0 Jan 19 22:15 /dev/ttyUSB0and here is the error:ERROR el.item.internal.GenericItemProvider - Binding configuration of type ‘serial’ of item ‘RFLinkRaw’ could not be parsed correctly.org.eclipse.smarthome.model.item.BindingConfigParseException: Could not open serial port /dev/ttyUSB0: Serial port ‘/dev/ttyUSB0’ could not be found. Available ports are:/dev/ttyACM0The same USB port still works with modbus binding, so there is no problem with the port itself or with the access rights. When USB0 is occupied by modbus, serial binding is configured with USB1 and the same kind of error is generated. As far as I know the right way is to edit /etc/default/openhab2Anyway, I’m checking what was passed to java and and see the right port list:root@zbox:# ps ax grep ttyUSB13078?
