Hi,
It's normal for em28xx to give you that sort of information on
device-plug - it does seem like a lot, but it's effectively "one-off"
and you probably won't see much else during use of the device, under
default module parameters. It's very useful log output if you have a new
device or a slight variant of an existing one, as it takes very little
effort to copy & paste the details here to help figure out how easy it
is to support the device.
But as you know, that device works already, so you can just ignore it :)
Regards,
Steve.

Hi,
I plugged my PCTV 290e device into my newly compiled 3.10.3 kernel today, and found this message in the dmesg log.

Presumably something this verbose is intended to be shared, so here it is. (I can't think of any other reason why this amount of information would be logged by default).
Cheers,
Chris
