v4l-dvb unsupported device: Conceptronic CTVDIGUSB2 1b80:d393 (Afatech) - possibly similar to CTVCTVDIGRCU v3.0?

[matteo sisti sette]

Hi,

I hope this is the right place for reporting this; if not, please
forgive and redirect me.

My DVB-T USB stick, a "Conceptronic USB 2.0 Digital TV Receiver"
CTVDIGUSB2 doesn't work after succesfully compiling and installing
v4l-dvb, and it seems it is not supported according to the device
list.

The ID is 1b80:d393

The name "Conceptronic USB 2.0" is very similar to that of CTVDIGRCU,
which _is_ supported and the chipset seems to be indeed an Afatech as
the output of lsusb reports:
Bus 002 Device 007: ID 1b80:d393 Afatech
(or isn't that reliable?)

So I wonder whether this is one of the cases where the following applies:
"The driver has to be aware that it's related to some hardware
(typically through the subsystem ID from the USB ID or PCI ID). If the
driver doesn't recognize/bind to your particular hardware, then the
module will probably load but then proceed to not do anything. In
other words, support for your device would have to be added to the
driver."

If I understand correctly (pleas correct me if I am wrong), IF that is
the case (which may be not), then making it work should be just a
matter of adding the id of the device to the source code of the driver
somewhere and recompiling it and it would work??

If so, is it something I may try following some step-by-step guide?

Thanks
m.

Matteo:

If I read this well, CTVDIGUSB2 1b80:d393 (Afatech) is not at all
similar to the CTVDIGRCU.
The CTVDIGRCU has a Realtek RTL2831U decoder, and is NOT included in the
standard dvb list.
Conceptronic just packages sticks from other vendors.
The fact that the device ID is recognized point towards the afatech
driver, and not the Realtek RTL2831U driver.

Fot background on the Realtek RTL2831U driver, see:

So is the table at http://linuxtv.org/wiki/index.php/DVB-T_USB_Devices 
incorrect?

It says:

Conceptronic USB2.0 DVB-T CTVDIGRCU V3.0 	
  ✔ Yes, in kernel since 2.6.31
1b80:e397 USB2.0 	
Afatech AF9015


Anyway, I see there are other sticks with chipsets by Afatech. Is there 
any chance that some of the currently implemented driver would work fine 
with my chipset if only I forced the driver to recognize the chipset as 
another one by touching the source code?
How could I try that? (if it deserves a try)

Thanks
m.

I see: apparently the versions earlier than V3.0 of CTVDIGRCU used 
Realtek RTL2831U. I'll make a note of that on the wiki page.

Thank you; indeed I provided incomplete information (i forgot the v3.0 
part).

Is it possible to force the driver to treat my chipset "as if" it was an 
af9015 and try and see if it works?

thanks

Is the CTVDIGRCU well supported by mainline? I think I can source
these locally.

Is the AF9015 driver stable? I've had very bad luck with 3 different
devices now.
