I hope this isn't too long for a first post to this mailing list, my
apologies in advance...
Decided to go nuts yesterday, picked this up at Frys on sale for $32 ish.
(Figured I could use some HD goodness to go with my trusty old M179s).
Kworld 340U PlusTV HD ATSC USB stick/ FCCID KW-ATSC 340U
ATSC only (no analog), unencrypted QAM cable, vestigal side band free
air (OTA HD).
USB ID is 1b80:a340
Uses an em2870, apparently (see below).
Tweaked the latest driver set I could find, lazily adding the basic
entries to em28xx-card.c so the USB ID would attract the em28xx driver.
(from mecurial repo http://linuxtv.org/hg/v4l-dvb)
(Haven't had this much fun in years, almost like Linux with random
hardware in 1994 again...)
First, with no args (modprobe em28xx)
dmesg says:

It always finds the audio, at least
I haven't programmed in years (wasn't good to begin with) but I will
gladly hack on this with some direction.
The windows driver CD had the following possibly useful info in the inf
file:
%USB2870.DeviceDesc.OEM4% = USB2870,USB\VID_1B80&PID_A340 ; Hybrid
ATSC <MXL5003s>
The included rom is named merlinC.rom.
The driver CD has a phillips tuner driver on it, saa713x, but looks
quite generic, not specific to this card, believe that would be for
analog which this card doesn't have.
