[pvrusb2] Getting error in increasing frequency

[Matt Nyerges]

I noticed this error a few times last year, but not much.  Recently,
however, I see this error a lot more.  Whenever it happens my program that
cat's /dev/video0 gets killed when the video0 file gets removed then added
back.  I wrote something that watches for this and resumes recording, but it
would be great to find out what is causing this.  Has anyone seen anything
like this?
