How do I passthrough USB devices to containers?

[vitaprimo]

I need to pass this protocol modem to a container, in regular Docker I think you'd just use the -v option to map it as a volume, but my attempts here have made the container non-bootable at all.

 

I made the container privileged (las time I did this, it was requirements for containers to access devices) and I was just going to map the path but I found a proper device option which I tried first. It failed. It also wasn't even available anywhere in the tree, I had to paste it because the / character is not typable whereas it is in other modes or in other fields.

 

 

I went back to trying adding the path as originally planed but it failed as well. I tried the documentation--nothing there, it guided me here.

 

Any advice to do this?

 

The device in the host/Unraid appears as /dev/ttyUSB0 as in the screenshot above.

 

Thanks.
