Did it ever work?  Which is the working kernel and which is the
broken kernel?

Yes, but I would suggest using lower resolution.

Did it work when you tested it?  Which kernel worked and which
kernel failed?

So on 3.1 low resolutions work for usbip but high resolutions don't.
As near as we can tell they never have, so it's not a regression.

File a bug on http://bugzilla.kernel.org explaining:
1) Which resolutions you tested (working and not working).
2) What you mean when you say it doesn't work.  What were the error
   messages etc?

When it comes time to move this out of the staging directory, we'll
look through bugzilla and see what bugs it has.

Hi David, 

Per your experience, what is the limit resolution for playing smoothly.
Do you think this is relate to the protocol of usbip?

Hi,

Both server and client are working at 100Mbps.

Hi,

I think we need to increase the depth of video buffers in UVC subsystem.

If I remember correctly, the usbip sugget using gigabit ethernet.
Since the maximum speed of usb 2.0 is 480Mb/s bigger than 100Mbps.
