Zigbee stick does not create /dev/ttyACM0 on USB passthrough #5084

Closed joshuakoh1 closed 3 years ago

joshuakoh1 commented 3 years ago

When I pass the USB device by device or by port to a VM, /dev/ttyACM0 disappears from proxmox host. But it does not appear on the VM at all. I only see the device under lsusb but no corresponding /dev/ttyACM0 device node.

Remove the passthrough, it shows up again under the proxmox host.

The dev node should pop up on the VM level but does not.

Proxmox has an option to pass a serial device directly but the USB stick only generates /dev/ttyACM0 but no /dev/ttyS0 so I cannot pass it through serialX.

Since zigbee2mqtt only reads from /dev/ttyACM0, even if I managed to pass it as /dev/ttyS0, I would still not be able to access it.

Hey, I'm afraid this is unrelated to zigbee2mqtt...

Since zigbee2mqtt only reads from /dev/ttyACM0...

That's not correct - you can have zigbee2mqtt connect to any serial device. For example, I'm using the following configuration:

serial:
  port: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

@piit79 I opened this because I'm not sure if it's related to the zigbee-herdsman firmware on the stick that's not allowing it to create the serial port after passthrough.

Still looking for a solution. When passed through, the USB device does not fire up cdc_adm.

@joshuakoh1 Have you fixed this?

joshuakoh1 commented 3 years ago

@ceesvanegmond Fixed? No. Bandaid solution? Yes. I passed /dev/ttyACM0 from the host to /dev/ttyS0 on the VM then made z2m read from there. Still no fix for the issue of the stick not creating any serial node on passthrough.

piit79 commented 3 years ago

Still no fix for the issue of the stick not creating any serial node on passthrough.

But this is unrelated to zigbee2mqtt... Possibly related to firmware, but this is not the firmware repository.
