[pvrusb2] HVR-1900 dvb-t problems

[Leonardo Muffatti]

Hi, Armin

I asked for revision because w_scan doesn't work only for D1F5.

I need to try patches at
http://www.mail-archive.com/linux-media@vger.kernel.org/msg05570.html

So i can trash my own patches

Best regards,  

	Leonardo

Hi Leonardo,

It is D1F5.

In the mean time, I did find the issue. It was another set of fixes. So not
so much the one that were pointed out.

But since Pietro Popoli probably just replaced his while code drop he, also
got the other ones.

Off-line Mike Krufky, indentified the issue. I then found the required
patches.
The following 4 patches were required:

Now I can tune dvbt as well.

However, I'm still curious as why you ask for the revision? You are
referring to the detection issue, where the EEPROM has a different ID?

Kind regards,

Armin

Hello Pietro,

Could you elaborate a bit more on what 'the changes are'.

I seem to have the same issue as you have: analog works, with digital
doesn't.
It loads the firmware, but finds no frequencies using w_scan. Using tzap to
tune to a know frequency doesn't produce a lock.

The patches however that you refer too, in case they are missing, would
however have caused the tuner not to load the firmware at all, as it
wouldn't detect the device at all.

I know this, as I had an older dvb drop, and had to apply these patches to
make the tuner to be detected at all. And indeed as elsewhere noted, if you
have a more recent drop, these patches are already in. The fact that you're
system already detected it, also suggests you already had these patches.

So the question remains, what solved it for you?

But correct me if I'm wrong here.

Regards,

Armin
