Looks like some innocuous logging from the ehci_hcd driver. I've never
seen it because I'm not using the ehci_hcd module on my systems.
When you tune a new channel, the USB transfer is stopped (with the URBs
still alive, so the driver "shuts down" them) and a new one is started.
Then the URBs are reused (instead of being deallocated/allocated
again/cleared as before) so they are resubmitted.

Ok, I don't have any problems so far - I also probably have some verbose/debugging usb options enabled in my kernel so I suppose others may never see these.
