I've attached the output of that command. Running it did not turn on the LED.
Strangely turning on the LED has become less reproducable now. It was on a moment ago after I resumed from STD and resumed from STR. But now that I turned it off the dd command I mentioned above does NOT turn it on again (nor does lsusb nor udevadm trigger --action=add)
So maybe half of the problem (LED switching on when accessing the USB device in any way) got fixed as a side effect of some other change already...
