Previous test was using a 3m long cable.

Tried again with a 1m cable:

I then tried again using the 3m long cable and got the same error as before
and connected at high-speed not SuperSpeed

Should I expect problems with a 3m long cable or does this say the 3m long
cable is faulty?

This is puzzling.  The device connected at SuperSpeed in the previous tests.
Clearly this is related to the warning in the preceding line (the port
failed to configure its link partner).

What could have happened?  A problem in the cable?

The usb-storage quirk setting would not have affected this.
