Hi !
I have problems with em28xx --- no signal in tvtime and xawtv:
kerne1 2.6.24.5
v4l snapspot: f1cc98803a31
device: intex gravity usb 2.0 tv box (works properly under XP) model No: IT-200USB made in China
lsusb output: Bus 001 Device 011: ID eb1a:2821 eMPIA Technology, Inc.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I guess Markus might know more about the em2821 chips.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I think it is misdetected. The V-Gear PocketTV is an em2800 chip whereas the usb id indicates an em2820 chip.
You might want to try to modprobe the driver with card=Nr

Where nr is one of the em2820 chips from:

Maybe one of those works.

I requested some more information about this one, though I'm currently busy with other devices which leaves only little time for this one..
