New unsupported device

Hi to everyone on the list,
this is my first post on the mailing list. I landed here after a lot of searching for a working driver for my DVB-T USB stick. I bought a Pinnacle PCTV Nano Stick (code: 73e) with HD capabilities, and I discovered that it came on the market very recently (less than one month ago).
As long as no google search, nor post search on linux-dvb mailing list had success, it looks this is my last chance to get my card working on GNU/Linux.

Here is the (actually useless) output I get from dmesg:
usb 1-1: new high speed USB device using ehci_hcd and address 5 usb 1-1: configuration #1 chosen from 1 choice

and here is my lsusb -v output about the card:
http://insomniac.slackware.it/lsusb.pinnacle.txt

In the hope that there's a light at the end of the tunnel, I thank you all for your patience and your work.

Best regards,

The best way you can help is to either tell us what the windows drivers are, or open the device up and tell us what is written on both the tuner chip and the main chip. They are generally the two biggest chips on the board and they have writing on the top.

I'm not sure about how to give you correct and detailed informations, as I'm not a Windows user, so correct me if I'm wrong. I cheched for driver details on Windows, and I see the following files:

BdaPlgIn.ax
drivers\BdaSup.sys
drivers\mod7700.sys

Tell me if you need more information, I'm very interested into make my card work and give back to the community all the support I can.

Look driver .inf files, they usually reveals better information. Anyhow, mod7700 could be DibCom 7700 chipset that is supported rather well.

The .inf should be this: http://rafb.net/p/8ideWc93.html

Anyway, can you point me out what is the module for such chipset? If it's included in the mainstream kernel, or if I need to get it separately. I have read about bttv.ko, but I'm not sure wheter it worked for me or not, because no device seems to be created in /dev, nor dmesg gives helpful messages after modprobe.
Thanks again.

I think it is not correct driver .inf file. inf-file you have is for Pinnacle PCTV 72e with product ID 0236 and lsusb you have has product ID 0237.

You are right. Here is the correct (I think) .inf
http://rafb.net/p/UFxQHw88.html

yes, thats correct. I made simple patch, you can test if it does something nasty. You can also look dib0700_devices.c file and try some changes. Patch can be applied towards current v4l-dvb-master.

Patched and recompiled the modules. Now plugging in the usb stick triggers the loading of the related kernel modules.
The one error I get in dmesg is

dvb_core: exports duplicate symbol dvb_unregister_adapter (owned by kernel)

Great :-)
Here my dmesg:

dvb-usb: found a 'Pinnacle PCTV 73e' in cold state, will try to load a

dvb-usb: schedule remote query interval to 150 msecs.

But another problem here:

w_scan version 20060902

and also:

 # ls /dev/dvb/*
 /dev/dvb/adapter0:
 demux0  dvr0  net0

/dev/dvb/adapter1:
demux0 dvr0 net0

So, no frontend is created. What may be?

Thanks,

That means the driver either couldn't work out what the tuner is and therefore, couldn't attach a frontend, or there was an error attaching the frontend. The next job is to work out what the tuner chip is, you might have to open it up and read the writing off the chip to find that out.

yep, tuner is missing. It could be mt2266. Look other devices in the file patched and try if some of those will work.

Pinnacle 72e was working, so looking on what you said a modification of the same driver should work with 73e... I will send the files later (I must find them...), because I think the changes needed where not added to the current v4l.

cd v4l-dvb
sudo cp firmware/dvb-usb-dib0700-1.10.fw /lib/firmware/ make all

Probably you will have to add the stuff that was being done in the previous patch to the source before compilation.

No one worked :-(
Neither Albert's suggestions gave a solution for my USB stick, I'm crawling in the dark..

Could you post your dmesg?

And your source?

It would be very useful if you could open your device and have a look on what chips it has inside. Just to check that we are in the correct direction.

It looks hard to open without breaking plastics. I tried today a couple of times, but if someone has experience in opening pinnacle cards, please tell me :-)

I tried both the tarball you pointed me out, and the latest sources from v4l-dvb hg repository. I applied the patch from Antti on both source trees and tried to load modules from both after make. But no one succeeded. If you need, I can post again the output of dmesg from the mainstream repository and from the tarball you gave me.

It's not clear that the patch worked with the differences of the source (it has a reference to the identifier matrix). I will try to add it just to check there's no problem with that. But tomorrw...

Yes, they differ, so I tried to patch by hand. In attachment the patch I did based on Antti's patch and your tarball (after a make clean). Don't really know if that makes sense in my case.
