 `OSError: [Errno 5] I/O error: '/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE-if00'`


There's an issue with your USB passthrough, the serial port isn't functional

It may have a USB descriptor but if software can't open the serial port and talk to it, it's likely a problem with your Unraid configuration

FINAL EDIT: My Solution.

The issue was how I was passing the USB through unraid to Hass.
Here's what worked for me:

  1. Turn off your Hass Host in Hardware (Shutdown Host).
  2. Go into your VM Settings, ensure Hass is off. Edit the VM and if you have the Conbee stick selected, deselect it. Hit Apply.
  3. Go to this post: https://forums.unraid.net/topic/113301-passthrough-of-conbee-ii-zigbee-usb-gateway-to-home-assistant-virtual-machine/page/2/
    They recommend that you insert this code into your VM Config:
    <serial type='dev'>
      <source path='/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_3DE24#####'/>
      <target type='usb-serial' port='1'>
        <model name='usb-serial'/>
      </target>
      <alias name='serial0'/>
      <address type='usb' bus='0' port='4'/>
    </serial>

  1. Go back in to edit your VM. Switch to Advanced in the top right. Scroll until you find </interface>. Create a new line, and paste the code above.

  2. We need to find your source path to enter above. Open an unraid command prompt and enter

cd /dev/serial/by-id/.

Then enter

ls

If your Conbee2 USB is connected, you should get an entry:

usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE######-if00@

Select this to copy it, and paste that in your <source path='/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_3DE24#####'/>

  1. Next we should doublecheck the port in target. Navigate to your UnraidIP/Tools/SysDevs and look under USB devices. If your conbee stick is listed as Port 1--X, then I think in <target type='usb-serial' port='1'> your port is 1, and you can leave it as is.
    The <address type='usb' bus='0' port='4'/> Does not need to be changed as this is configuring what Hass will see the port as.

  2. Save/Apply and restart the Hass VM.

  3. Open your Home assistant and got to /config/hardware. Click the 3 dots, click "all Hardware" and look for your USB. For me, it no longer shows up as my Conbee... instead, it shows up as:

/dev/serial/by-id/usb-QEMU_QEMU_USB_SERIAL_1-0000:00:07.7-4-if00-port0

  1. Now you can go to your Integrations and set up ZHA. This worked for me and i got my network back. Albeit, I had to re-rename everything. Which was a pain.

Let me know if this helped you.

Some Extra Notes:

I switched back my VM to q35 v4.2, as per the post I linked. Unsure if that also helped.

When I open the log for my Hass VM, I am getting this error: Domain id=13 is tainted: custom-ga-command. It seems that despite this, everything is working correctly.

My FINAL WORKING Unraid VM config. I took out the serial after DE and replaced it wil #s
