Fix/Add: device reset command

[systemcrash]

When my Conbee2 is connected to my Synology NAS, and the device reboots (software update, whatever), Docker images lose contact with the device.

The device still shows up as:
/dev/ttyACM0

And Synology Info shows the device info as connected i.e ConBee2 etc. But none of the HomeAssistant docker images, despite full access to the device, can find it.

Only physically unplugging and reconnecting it works. ( No need to issue any commands or restart any docker images ) Then the device shows up in ZHA Home Assistant etc.

So warm reboot - device no longer available.
Cold reboot or hot-plug - device available.

Is there an available command to 'reboot' the USB device?

I do not understand the implications of
0x26 | Watchdog TTL
"By writing a lower value like 2 seconds, the firmware can be rebooted."

Which firmware? The ConBee?

Also, what can we expect is a reasonable reboot time for the firmware, if it is the ConBee?
