Subject: xhci_hcd debugging status, please?

Hello,

Can someone please summarise the status of the xhci_hcd debugging I
found after booting into 3.12.2?
I did not see these messages before and I do not yet understand the
added value for a mere user of this exciting xhci technology.
Can we please have them go away if really there's noting really wrong?
See below for a small part of the stream of stuff that was started.

Kind regards,
Udo
