USB pass through not passing through

[u/Western-Maybe-5747]

Hello,

I have Home assistant running on my Synology DS1621+ as a virtual machine and I have been running a Sonoff Zigbee Dongle E which I had successfully set up and passed through to Home Assistant.

Whilst pottering in home assistant and looking at new integrations I happened to notice that my ZHA integration had disappeared. No problem I thought, I will re-add the integration and all will be well…..

I now can’t get my sonoff dongle showing at all within Home assistant as a device, even though it shows as successfully passing through to the virtual machine.

Can anyone help me establish my serial device path? I know it is passing through ttyUSB0 but trying the usual /dev/ttyUSB0 as the device path fails to connect.

The device is showing correctly in the pass through settings for the virtual machine but I can’t get it to show under settings/system/hardware in home assistant. Dongle seems to be working fine as i can connect it to sonoffs firmware updater and successfully update firmware.

SSHing into my synology and following a few guides online is showing it successfully connected to my NAS and drivers are installed correctly. Pulling my hair out as this was previously working flawlessly!!

In Home Assistant go to System -> Hardware. Click "All hardware", and search for USB. Does your device show up there?

Can you point out the show all hardware button as all I seem to see is processor and memory use graphs!

Do you have the USB driver installed for your Synology? They removed it with DSM7, but you can reinstall it. I’ve personally only used these ones but this seems like a solid guide.

Yes I have them installed and I’ve gone to the trouble of reinstalling them again yesterday to no avail.

The sonoff is showing as a connected device on the NAS and shows as an option to pass through to my VM

I will have a look at the mariushosting guide as I followed a different route of installing them via terminal and ssh. Maybe this is the issue, thanks Ainen
