I did a cold reboot of Home Assistant this morning and the Sonoff Zigbee 3.0 USB Dongle is no longer connecting (didn’t change any configurations, just rebooted network, routers and HA).
Error is:
Failed setup, will retry: [Errno 2] No such file or directory: ‘/dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_c8b7e548470dec119936d5cebd930c07-if00-port0’
I have the dongle attached via Ethernet Cable (USB to Ethernet) I’ve checked all cables and everything is fine.
I installed all pending updates to HA and rebooted, still nothing.
Adding my similar experience. After physically shifting my Sonoff dongle E without disconnecting anything, I noted this error the next day. Tried HA restart then HA reboot (RPi 4) but didn’t resolve. Then I unplugged the USB cable from the dongle and reconnected, and error immediately disappeared and hasn’t returned.
Maybe the error is triggered by a USB connection issue, which disconnecting and reconnection would resolve (for both straight USB and USB-etho).
