Brief summary

The laptop wakes up from suspend, plays USB plug in/out sounds

How reproducible

Happened only once and I couldn't reproduce it again in three retries.

How to reproduce

Suspend the laptop with the docking station connected. The docking station has an audio jack, a USB keyboard, two USB flashdrives, Ethernet cable and a Display Port display connected via usb-c.

Expected behavior

The device should enter suspend (power diode blinking rhythmically) after a while and wake up after pressing some key / touching the touchpad etc.

Actual behavior

The power diode was blinking irregularly, sometimes the ON state was shorter, sometimes it was so long I tought the device mighy have woken up from suspend. The irregularities in the blinking were accompanied by the sounds of a USB device being plugged out and plugged in immediately after the "out" sound ended.

Screenshots

No response

Additional context

I haven't recorded this phenomenon. Probably the issue should be closed after a while if no one else experiences this behavior because I have no idea how to reproduce it.
