Insteon Integration setup won't let me enter the USB device path

I’m running HA 2023.10.3 in a Docker container on a Pi4. There is a PLM modem hooked to one of the USB ports that has worked in the past. I just reinstalled almost everything but setting up the Insteon PLM is not working. I get the pop-up to enter the USB device path but there isn’t any place to actually enter the path. I’ve tried this both on my Linux box running Chromium and on the Android app. Neither has a place to enter the device path. I know my Insteon worked early in the year, but sometime before 2023.07, it seems to have failed. Anyone have a fix?
