Debugging zigbee messages not making it through the coordinator (20240710)

[deviantintegral]

I've had the following happen twice in the past few weeks that makes me think there is a bug in the 20240710 firmware. But, I'm stuck on next steps.

Environment

• zigbee2mqtt 2.0 (dev branch from ~2 weeks ago)
• herdsman 3.0.4
• Sonoff Dongle P with 20240710 firmware.

Symptoms

• A zigbee switch (https://www.zigbee2mqtt.io/devices/43076.html#enbrighten-43076) responds to on / off commands, but the replies to the command don't make it back to Zigbee2MQTT. The switch eventually shows up as offline.

Debugging information

• Debug logs from herdsman show no response from the switch.
• A local sniff shows that the switch is sending through a Philips Hue bulb which has a direct connection to the coordinator.
• The sniff also shows the Hue bulb relaying the message to the coordinator.
• Restarting zigbee2mqtt does not fix the issue.
• However, reinserting the dongle in the USB extension cable to reset it does fix this issue! A sniff showed the route through the Hue bulb remained the same, and all devices kept the same short network IDs.

This has me thinking that the problem is in the coordinator firmware. It's hearing the message, but is never passing it back up to Herdsman.

This is clearly an issue that doesn't happen often, otherwise I'd expect to be seeing it daily with reports from other users. Is any way to do some sort of debug log from the coordinator itself? A way for it to pass up error information if it hits limits of some kind?
