ws28xx: ValueError: The device has no langid (debian in LXC)

[michael.k...@gmx.at]

I've just tried to get my ws28xx running on a debian installation running in a LXC on a QNAP NAS.

dmesg shows the dongle was connected:

[297714.611821] usb 1-2: new full-speed USB device number 4 using xhci_hcd

When I start wee_device or weewx I get this exception:

Is this related to the LXC? Any ideas?

Same Problem.

I try to change from WS-2300 to WS-2816

It's a problem of accessrights.

For my WS-2300 I have to add following to the lxc config file to have full access to the USB2Serial Adapter bind to /dev/ttyUSB0:

lxc.cgroup.devices.allow: c 188:* rwm

lxc.cgroup.devices.allow: c 189:* rwm

lxc.mount.entry: /dev/ttyUSB0 dev/ttyUSB0 none bind,optional,create=file

But I don't know what should be configured for the WS-2816, because in the syslog there is no Information, which Device I have to use to configure in the lxc configfile

[F. S.]

For me, I solved the problem.

lsusb on the server (Proxmox, QNAP,...)

Bus 001 Device 004: ID 6666:5555 Prototype product Vendor ID

ls -l /dev/bus/usb/001/004
crw-rw-rw- 1 root root 189, 3 May 24 18:48 /dev/bus/usb/001/004

Then in the lxc configfile: <CT#>.conf enter these two lines:

lxc.cgroup.devices.allow: c 189:* rwm

lxc.mount.entry: /dev/bus/usb/001/004 dev/bus/usb/001/004 none bind,optional,create=file

In weex.conf:

[Station]
............
station_type = WS28xx

[WS28xx]

    # This section is for the La Crosse WS-2800 series of weather stations.

    # Radio frequency to use between USB transceiver and console: US or EU

    # US uses 915 MHz, EU uses 868.3 MHz.  Default is US.

    transceiver_frequency = EU

   # The station model, e.g., 'LaCrosse C86234' or 'TFA Primus'

    model = LaCrosse WS28xx

    # The pressure calibration offset, in hPa (millibars)

    pressure_offset = 0

    # The driver to use:

    driver = weewx.drivers.ws28xx

reboot weewx Container
