I tried to manually add insteon to configuration.yaml and I noticed the following log error:

Logger: pyinsteon.protocol.serial_transport
Source: /volume1/@appstore/homeassistant/env/lib/python3.8/site-packages/pyinsteon/protocol/serial_transport.py:24
First occurred: 11:30:35 AM (1 occurrences)
Last logged: 11:30:35 AM

Unable to connect to /dev/ttyUSB0: [Errno 13] could not open port /dev/ttyUSB0: [Errno 13] Permission denied: '/dev/ttyUSB0'

Here are the permissions:

ls -le ttyUSB0
crw------- 1 root root 188, 0 May 27 10:26 ttyUSB0

[BenjV]

change the permissions of ttyUSB0 to 666 (rw for everyone)

[rdagger]

@BenjV the permissions did not persist and it did not seem like best practices.

I solved the problem as follows-->

Determine the idVendor and idProduct of USB modem:
sudo lsusb -v | grep 'idVendor\|idProduct'

Results:

idVendor 0x0403
idProduct 0x6001

Create new udev rule file:
sudo nano /usr/lib/udev/rules.d/99-usb-serial.rules

Add the following to the new file which adds Home Assistant group permission only to the USB modem:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", GROUP="homeassistant", MODE="0660"

Restart Synology after saving and exiting the new file (reloading udevadm was not sufficient)

After reboot check USB permissions:
ls -le /dev/ttyUSB0
Results:

crw-rw---- 1 root homeassistant 188, 0 May 28 10:11 /dev/ttyUSB0
