Configuring insteon PLM - USB Device Path?

apologies if this has been discussed… definitely a “newbie” here. I have been using indigo for years as my server and would like to switch to HA now.

I am running home assistant on my synology NAS device. When I try to add the insteon PLM, I get a dialogue box asking for the USB path and I’m stuck. I have asked other friends with the same setup and they have not gotten this dialogue. I am running the device with high priority so it should have access to the USB ports. If anyone can point me in the right direction, I’d be thankful!

Here’s a thread that should help.

Insteon USB PLM path

For me, the solution was “/dev/ttyUSB0” (no quotes).
