Pinnacle PCTV DVB-T 70e

Pinnacle PCTV DVB-T 70e

[Alexjan Carraturo]

Hello everyone,

My name Alexjan Carraturo and am new to this list, and I apologize if
my first request for assistance infringe some custom.

Long time I try to run a particular type of device DVB-T, and sometimes I did.

The device in question is a Usbstick Pinnacle PCTV DVB-T (70th); is
USB, running lsusb we have this

eb1a:2870 eMPIA Technology, Inc. Pinnacle PCTV Stick

As I said before, once I managed to get it working with both Fedora
and Slackware (the Linux distributions that I use routinely).

Did not work with the drivers on the kernel (em28xx, em28xx-dvb); the
"traditional driver" try to recognize the device, but doesn't work.

The device works only (and very well) with a version made by some
individuals, called em28xx-new. There is a version of these drivers,
compile manually, but it works only until kernel 2.6.31 (
http://launchpadlibrarian.net/35049921/em28xx-new.tar.gz )

Searching the internet I saw that many users are trying to work this
board (very common).

Is there a way to incorporate the changes mentioned in the official driver?
Or, you can suggest how they might be modified drivers indicated to
work with recent kernels (2.6.32, and soon 2.6.33 or later)?

Thank yuo

Alex.

Hi Alex,

this list is all but dead. Use the linux-media mailing list instead (I
have cc'ed my reply to it).....in the olden days, the video4linux list
was the correct one for analog devices, and linux-dvb for (surprise,
surprise) dvb related discussion. Nowadays, they have both been
superseded by the linux-media list.

He stopped supporting his driver and now only works on closed source
software.

No.

The person in question, unfortunately and needlessly, came to an impasse
with the v4l-dvb project. He later stopped developing his work. And no
one here is much interested in touching his with a hundred and ten foot
pole.

You can, however, look to see if you can add support for your device to
the existing v4l-dvb kernel driver. There are several developers that
are knowledgeable of the em28xx driver, and whom may be able to help you
in that regard, but you will have to gain there attention first.

And I think this is the point in question. No longer working on this driver.

Why not? Because nobody can cure this entry? Or why the driver is not
compatible with the version in the kernel now?

I'm sorry, but even knowing a bit 'of the C programming language, I
have never written a driver, I'm not able, and I honestly do not even
capable.

You tell me to add support to the current driver, but I have no idea
how to do. It is also good to clarify that the driver on the kernel
vanulla charge in the presence of this card, but simply does not work,
and does not create deivce (/dev/dvb/).

So knowing that I'm not able to write the driver, I would say that
this device is definitely dead and buried ... in this case would be at
least that was not loaded em28xx module (the one in the kernel),
avoiding giving the illusion that the driver functions.

I do not know if you can, but should be added, if any, in a sort of blacklist.

For someone to add support to a device, it needs to have that device (or
a similar one), and to be able to get access to the datasheets or to use
some reverse engineering technique. One important information is what
are the chips inside the device.

Take a look at linuxtv WIKI pages. It explains several useful things
on how to add support to a new device.

The USB ID used by your device is generic: all devices with em2870 without
eeprom will inform the same code (and even some with eeprom, but where
the vendor didn't care to write their own ID there).

What are the components used on your device?
