Never mind my last two posts. I applied the patch Gennar1 provided to the checkout from Ambrosa's git repository and the device is working fine now. It would be great if the patch could be added to the repository, in order to make the installation process easier.

Great work to anyone involved.

Please help with adding Support for 1b80:d393 Afatech DVB-T receiver [RTL2832U]

Hi I am trying to get a couple of these USB DVB-T Tuner sticks working under Mythbuntu 12.04.
They are Gigabyte U7300 Model USB 2.0 devices and they appear in lsusb as
1b80:d393 Afatech DVB-T receiver [RTL2832U]
I am wondering if I can help you to add support for these in your module.
My current Kernel is 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
I cloned your repository and built the module all ok and it load without a problem, however in dmesg it complains that no fronted was attatched.
I guess the module does not know about this particular tuner?
BTW I am in Australia.
dmesg from immediately after boot output is as follows

Your device PID is already supported, but it is shared by several different products.

The dmesg error is clear:

[ 139.584406] RTL2832U check_tuner_type : ERROR Unknown tuner on board...

The rtl2832 driver supports 10 different tuners, but probably your device is using a new tuner type. Other devices with the same PID usually come with the fc0012 tuner; maybe you have a new revision of this tuner that is not supported yet.

Can you open the device? It would be interesting to see a picture of the PCB.
Anyway, your best chance to get it supported is to ask Realtek for an updated driver with support for the new tuner.

Hello,

I also have a RTL2832U chipset based DVB-T USB tuner. Its name is "Twintech UT40" but my VU+ Duo recognize it as an Afatech :

Bus 001 Device 007: ID 1b80:d3a4 Afatech
iProduct 2 Rtl2832UDVB
iSerial 0															

I'd like to install the driver but it is not in the plugin list nor the package list. Do you think Your driver could work ? Where could I find an IPK ?
Thanks,

Hi,

it's my first post here, hello

I'v bought a AUGUST DVB-T205 USB Stick with a RTL2832U chip.
lsusb say:
ID 1f4d:a803 G-Tek Electronics Group
They give source code at:
http://www.augustint...river_linux.zip
But with linux 3.0.0 they didn't work...

Can you made something please?

ps: I've test your work but when a made a modprobe, he give me a FATAL ERROR.

The driver works well for me with the ezcap EzTV USB 2.0 DVB-T/DAB/FM dongle (Realtek Semiconductor Corp. RTL2838 DVB-T) on Ubuntu 12.04 64bit - have you considered submitting it to Linux staging?

Thanks for your help

But I do not know how to install/compile the driver or patch it :-/ ...
Is it possible to make an IPK installer or something simpler than all this stuff ?

Hi nico,
1f4d:a803 is alredy supported by the current driver. If Ambrosa's git does not work on your kernel, your best option is to use the media_build driver tree and apply the patch over it (see the older posts).

[Gennar1]

The patch is not complete, as you have to add also a new board description to the driver (or add the new USB ID to an existing board description). Anyway, it's not needed at all, as 0x1b80:0xd3a4 is already supported.

The driver works well for me with the ezcap EzTV USB 2.0 DVB-T/DAB/FM dongle (Realtek Semiconductor Corp. RTL2838 DVB-T) on Ubuntu 12.04 64bit - have you considered submitting it to Linux staging?

There is a completely new driver for the rtl2832u demodulator, written by Thomas Mair, which is currently under heavy development and will be probably merged in the upcoming 3.5 kernel. Currently it supports only 2 tuners, in spite of the 10 tuners supported by the Realtek driver, but things will get better in the future. As soon as it will be mature enough, I will backport it to the OpenPli kernel.

Hi Cyb,
unfortunately, currently there is no ipk package for the rtl2832 driver on VuPlus kernels on OpenPli images.
You may want to check other images (Vix? SifTeam?) but I'm sure if they are including this driver in their images.

[cyb]

Hi Gennar1,

I've temporary replaced the .conf opkg feed files of OpenPLi with the VIX ones. And after an opkg update, I've found a driver for RTL2832 that I managed to install via Telnet.
And... Everything works fine ! My two USB tuners are working without any problem

Too bad this driver is not in the OpenPLi feed !
Anyway, thanks for this tip !

lsusb:

Bus 002 Device 005: ID 1d19:1102 Dexatek Technology Ltd. DK mini DVB-T Dongle

Yes, your device is supported (well, its VID-PID is in devices list).
See here https://github.com/a....0.0/rtl2832u.h row 26 and 28

@ambrosa: under OpenPli 3.0 will be possible using it for DMM with new kernel too ?

[Gennar1]

For sure, no problem. Just take the et9x00 patch and adapt it to the DMM kernel. Only minor manual editing to the dvb-usb Kconfig/Makefile files could be required.

OK, I will try it.

While you are looking into it, you may want to port all the DVB driver patches to the Dream kernels. Just take the ET patches for kernel 3.2 here:

http://openpli.git.s...ac0b1b21241a188

and apply them to the new Dream kernels. They should apply without any editing as the kernels are pretty much identical.
Then you just have to compile again the new kernel and retrieve the new ipk packages. If this packages work fine, the patches could be committed to the Dream tree.

[ims]

What all is then needed for trying dvb-t usb ? Some plugin or usb tuner is added to Setup - Service Searching - Tuner configuration ?

[pieterg]

things are integrated in e2, so you just need to download the driver ko (and possibly firmware), modprobe the driver, and restart e2.

[ims]

can i update older ( yesterday's) kernel manualy with ipk from my PC too or must I flash with whole new firmware ?

[ims]

Why was Q about new flash: after build todays clear firmware (removed whole tmp) and flash, there is so much errors for several plugins ( some with header and python 2.7 and some with md5), f.eg. softwaremanager too... => I put back my yesterday's image, install manualy kernel.ipk, module, modprobe and it seems, now it searching dvb-t programs (16 programs - include radio). And works
