I’ve been experiencing repeating issues in #HomeAssistant with devices not responding. It’s been manifesting in the system log as an error:

cp210x ttyUSB0: failed set request 0x12 status: -110

That’s Zigbee dongle. The workaround was to reboot the system, but I’ve changed it’s USB port and it seems to be gone.

The system is #RaspbianOS on #Raspberry Pi5. Pi is powered via PoE and it should have sufficient power budget, though it’s running of an nvme.2 and with USB hard drive, so who knows…

@ssamulczyk I had to move my Conbee II stick to a powered USB-hub to make it stable on the Pi4...

@fhekland Yeah… My issue came back, though restarting HA was enough to fix it.

I’m now trying and old unpowered 2.0 USB hub I had laying around… We will see…

@ssamulczyk Ahh, sucks. Unless you can switch to the original power supply, perhaps you can tweak the power negotiation via config.txt?
I don't know if there is a cap on the input current for PoE on the Pi, but worth a try... https://forums.raspberrypi.com/viewtopic.php?t=367681

@fhekland Yeah, I’m doing this as well, because without it I had issues with external USB drive…🤷🏻‍♂️
