The USB hub is brand new. Honestly, I don't even know how to trigger
this bug; it happens completely randomly.
The chip does not overheat. I performed a stress test using iPerf,
where the router acted as the server and my machine as the client,
receiving traffic at 1 Gbps with 10 parallel streams. Simultaneously,
I kept a USB flash drive in the hub, continuously reading data from
it. The system remained stable for over 30 minutes without any issues,
then I terminated the test.
This specific crash today occurred right after downloading 900MB of
packages. Apologies for the previous log; this time I have attached
the full journalctl log for better context.

Looks like the device disconnected right after booting, not after being
used for a while.  Are you sure that was the correct log?

thanks,
