Add support for USB TTY devices

[tedivm]

I'm trying to get Docker Swarm working with zigbee2mqtt. To get the zigbee radios working in swarm their documentation recommends a method that came from this github issue. That solution doesn't work anymore, but it led me to your container.

First off, I super appreciate that you built this! It is going to make some IOT stuff a lot easier.

The problem I'm running into is that the program currently skips over my USB radio. I'm using a HUSBZB (on a Nortek device that has it and a zwave controller), which exposes the devices on /dev/ttyUSB0 and /dev/ttyUSB1 (which I've mapped with some udev rules to /dev/zigbee-serial and /dev/zwave-serial)

2023/07/11 02:56:53 The cgroup path for process 122087 is at /host/sys/fs/cgroup/system.slice/docker-686570ecb1719d1d14cbebfe1f056ba83c1f55278d59dcc861eece6c721553c5.scope
2023/07/11 02:56:53 aborting: device is neither a character or block device
2023/07/11 02:56:53 unsupported device type... aborting

I am an absolute newbie when it comes to Go, otherwise I would try resolving this myself. I'm super happy to test out branches or dev code on my local machine.

I’m guessing it’s because the device paths are symlinks to the original devices? Have you tried volume mounting the original /dev/ttyUSB* paths for testing purposes? Could you do an ls -l for the devices in question?

I just made a change to the repo. Download it and build and see if it works for you.

Thank you, it works perfectly now!
