I am trying to run weewx on a container in ProxMox. I can do lsusb, find
the device, and properly forward it to the weewx container. It starts up
and works just fine. After a short while (exact time unknown) the "Device"
number increments on lsusb, which disables the forwarding of that device.
I'm not sure if it is a programming issue or acurite issue, but I need to
permanently forward that device to the container. Currently, I have a
symlink created and set to /dev/acurite in the host and forwarded to the
container, but I need a script or something to forward /dev/acurite to
/dev/bus/usb/002/XXX that changes when it increments.
Unless I can put into /weewx/bin/weewx/drivers/acurite.py to JUST use the
/dev/acurite device, but I don't know that much Python programming.
*UPDATE*: Apparently when it gets a new "Device ID" the Container does not
update the major/minor numbers, and has to be rebooted to re-connect. Any
idea why it keeps incrementing the Device Number?
Any help is appreciated.
Thanks
Ryan
