As this new event does not have "disabled by hub (EMI?)", it is a
different problem to your 19th October post, so I don't think the
patch is relevant.

If the other USB ports are not responding, then your problem is
probably wider than the wireless device, and the wireless device
is acting as the "canary in the mine"; failing first because it is
the most active.
Can you test to exclude possibility of damaged USB host controller or
hub?

Yes, once a USB host controller is failed, organised reboot can be
difficult. lsusb not updated confirms host controller not responding.

Your dmesg looks like you removed and reinserted the wireless device
several times. Did you do that, or did the system do it without any
physical action?
A full dmesg from boot may be interesting, at least to better
understand the USB host controller.
