Hello,
unfortunately I do not understand development, patching, compiling things.
I have try it but I need more help.
I have done:
git clone --depth=1 git://linuxtv.org/media_build.git
cd media_build
./build
it downloads and builds all. At begin of compiling I had stop it.
Then I did manual change of
./media_build/linux/drivers/media/usb/dvb-usb-v2/af9035.c
------------------- old part:
{ DVB_USB_DEVICE(USB_VID_TERRATEC, 0x00aa,
&af9035_props, "TerraTec Cinergy T Stick (rev. 2)",
NULL) },
/* IT9135 devices */
#if 0
{ DVB_USB_DEVICE(0x048d, 0x9135,
&af9035_props, "IT9135 reference design", NULL) },
{ DVB_USB_DEVICE(0x048d, 0x9006,
&af9035_props, "IT9135 reference design", NULL) },
#endif
/* XXX: that same ID [0ccd:0099] is used by af9015 driver too */
{ DVB_USB_DEVICE(USB_VID_TERRATEC, 0x0099,
&af9035_props, "TerraTec Cinergy T Stick Dual RC (rev.
2)", NULL) },
----------------------------- new:
{ DVB_USB_DEVICE(USB_VID_TERRATEC, 0x00aa,
&af9035_props, "TerraTec Cinergy T Stick (rev. 2)", NULL) },
/* IT9135 devices */
{ DVB_USB_DEVICE(0x048d, 0x9135,
&af9035_props, "IT9135 reference design", NULL) },
/* XXX: that same ID [0ccd:0099] is used by af9015 driver too */
{ DVB_USB_DEVICE(USB_VID_TERRATEC, 0x0099,
&af9035_props, "TerraTec Cinergy T Stick Dual RC (rev. 2)", NULL) },
--------------------------------------------
But now I do not know how to "restart" build process.
I have try:
cd /tmp/media_build/linux
make
It had compiled *. and *.ko files.
Then I have copy the new
dvb-usb-af9035.ko to kernel modules dir
And the result is:
# modprobe -r dvb_usb_it913x
# modprobe -v dvb-usb-af9035

What do I wrong ?
How to do it correct ?
- probably I should add patch file to
./media_build/backports
But I need the correct patch file with correct name of it ?
And what about modification of ./media_build/backports/backports.txt ?
Sorry that all is over my knowledge.
And it is not possible somehow to add new_id without patching ?
echo 048d 9135 > /sys/bus/usb/drivers/dvb_usb_af9035/new_id
bash: /sys/bus/usb/drivers/dvb_usb_af9035/new_id: Adresář nebo soubor
neexistuje
the file do not exist.
Why ? At my wifi dongle it has work.
Thanks for helping.

Hello,
I have this:
http://linuxtv.org/wiki/index.php/ITE_IT9135
with dvb-usb-it9135-02.fw (chip version 2) on U12.04 64b with compiled
newest drivers from:
http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers.
The problem is - after some time I receive a program (e.g. in Kaffeine,
me-tv, vlc, ...) the program get more and more damaged and finely get
lost at all.
I happens quicker (+- after 10-20 minutes) on channels with lower
signal. On stronger signals it happens after +- 30-100 minutes.
The USB stick stays cool.
I can switch to another frequency and back and it works again OK - for
only the "same" while.
Could that problem be in (or solvable by) FW/drivers or is it
!absolutely certain! "only" HW problem ?
In attachment is output from tzap - you can see the time point where the
video TS gets damaged.
Any suggestion ?
Thanks --kapetr
Could you test AF9035 driver? It support also IT9135 (difference between
AF9035 is integrated RF tuner, AF9035 is older and needs external tuner
whilst IT9135 contains tuner in same chip).
Here is example patch how to add USB ID to af9035 driver:
