Dazzle TV Hybrid USB and em28xx

Dazzle TV Hybrid USB and em28xx

[Giuseppe Borzi]

Hello to everyone,
I bought a Dazzle TV Hybrid USB stick some years ago (2006 maybe?) and until
now I've used out of kernel drivers from M. Rechberger. Here's a webpage about
the stick

http://www.lelong.com.my/Auc/List/2009-10DeStd44780009_AUCTION_-#
Dazzle-TV-Hybrid-USB-stick-Watch-TV-without-Internet-BID-Now.htm
(this line has been breaked at the sharp # sign)

The usbid is eb1a:2881.
The Linux distribution I'm using, Archlinux, has updated the kernel to 2.6.31.3
and I've failed to patch the out of kernel drivers again, so I've tried the in
kernel em28xx modules.
These are the results: when I plug the stick em28xx and em28xx-dvb get loaded
by the kernel, I think the stick is recognized as card=53 (Pinnacle Hybrid
Pro), and the /dev/videoX, /dev/dspX, /dev/vbiX and /dev/dvb/adapterX devices
are created. But analog TV has no audio (I've tried sox/arecord-aplay),
teletext doesn't work (mtt segfaults) and DVB doesn't work too. With me-tv I
get an error message like "Failed to tune to channel" and sometimes a
"timeout".
Searching this mailing list I've found a way to get at least DVB working
(thanks to Emanuele Deiola)
1) remove em28xx-dvb and em28xx modules if these are already loaded;
2) plug the stick (the kernel loads em28xx and em28xx-dvb);
3) remove em28xx-dvb and em28xx modules
# modprobe -r em28xx-dvb
# modprobe -r em28xx
4) load em28xx with card=11
# modprobe em28xx card=11
and DVB works, i.e. me-tv, vlc, w_scan work as expected. Analog TV is still
without audio, video is OK.
I've tried to add the option card=11 in modprobe.conf but the result is that
the /dev/dvb/adapterX directory is not created.
I hope this is helpful for other people with this stick and to the developers
to enhance support for the stick. Please developers let me know if you need
more info.

Make sure you have the latest v4l-dvb code installed.  The changes for
that board went in relatively recently (make sure you do *not* specify
a card= modprobe parameter).

Make sure you have the correct standard selected.  This sort of thing
often occurs when you are in an area with PAL support but you have the
device configured for NTSC.

Teletext is not supported currently - I did the NTSC VBI support and
am planning on doing the PAL support in the next couple of weeks.

A fix for this was done this week (but hasn't been checked in yet).
Check the linux-media archive for the PCTV 320e thread.

Thanks for your prompt reply. I've downloaded v4l-dvb-5578cc977a13.tar.bz2, but
it fails to compile when it reaches firedtv-1394.c. The first part of the error
message is

/home/gborzi/v4l-dvb-5578cc977a13/v4l/firedtv-1394.c:21:17: error: dma.h: No

what follows are several warning and error messages about implicit declarations
and "dereferencing pointer to incomplete type" related to the lack of the above
include files.
I'll try again after configuring the compilation to avoid that error message, 
i.e. by compiling only the modules I need for em28xx.

Yeah, that happens with Ubuntu Karmic.  The v4l-dvb firedtv driver
depends on headers that are private to ieee1394 and not in their
kernel headers package.

To workaround the issue, open v4l/.config and set the firedtv driver
from "=m" to "=n"

Thanks Devin,
following your instruction for firedtv I've compiled
v4l-dvb-5578cc977a13 but the results aren't so good. After doing an
"make rminstall" , compiling and "make install" I plugged the USB
stick, the various devices were created (including /dev/dvb) and here
is the dmesg output (now it's identified as card=1)

then I started checking if it works. The command "vlc channels.conf"
works, i.e. it plays the first channel in the list, but is unable to
switch channel. me-tv doesn't start, but I think this is related to the
recent gnome upgrade. w_scan doesn't find any channel.
Analog TV only shows video, no audio. Tried this both with sox and vlc.
When you say that I have to choose the right TV standard (PAL for my
region) do you mean I have to select this in the TV app I'm using
(tvtime, vlc, xawtv) or as a module option? I've not seen any em28xx
option for TV standard, so I suppose it's in the app.
Finally, I've noticed that the device is much less hot than it happened
with out of kernel modules and the card=11 workaround.
Is your latest post "em28xx mode switching" related to my device?

Open v4l/em28xx-cards.c and comment out line 181 so it looks like:

//        {EM2880_R04_GPO,        0x04,   0xff,          100},/*
zl10353 reset */

This is an issue I have been actively debugging for two other users.

Correct - the em28xx module does not have module parameters for the
standard - you have to select it in the application.

Yes, it is one device effected by that discussion.

Thanks Devin,
now DVB works as expected, i.e. I can change channel and w_scan
finds the channels available in my area. The stick is recognized as
card=1 instead of 53 as I expected, but still it works fine.
Still no sound for analog TV, but that's a minor problem.

Thanks again.

Can you please provide the output of dmesg after connecting the card?
I am not sure why it would recognize as card=1.  Do you have a
modprobe option setup forcing it to card=1?
