Hi!

I've merged the code for the 340e, that Devin Heitmueller made over at
Kernellabs, with the latest HG tree and tested it on Ubuntu 10.10
today (2.6.35-22-generic).

I lack the knowledge on how to add the new files (xc4000.c and
xc4000.h) to a patch, so the script added in the tar ball just copies
it to the right place, the firmware has to be manually copied too.

Just want to share an alternatives, patches to vanilla kernel 2.6.35;
by me, which I sent to Istvan Varga. 

http://istvanv.users.sourceforge.net/v4l/xc4000.html


I am using PCTV 340e with GNU/Linux since Devin Heitmueller's
"Christmas present" in kernellabs.com last year. I did few portings to
make the driver workable with vanilla 2.6.34 and later. 

Beside's Devin's xc4000.[ch], I also use the files (xc4000.[ch] and
firmware) from Istvan page. It works very well and the dongle feels
much cooler when idling. because the PCTV 340e's power management is
working. 

Since there are several devices using xc4000 driver; I really hope
that it can included in main v4l stream; at least in the staging
directory. 

Also really like to see analog support (S-video capture, analog TV and
FM radio) for PCTV 340e too :). I was told that the dib0700 driver
does not has the analog tuning yet.

Thank you

Tried "your" code today and it works slightly better since the tuner
still works after a reboot.
The remote stops working tho. I get this in dmesg: "dib0700: rc submit
urb failed".

Can't say I notice any difference on how warm it becomes tho.

Thank you for trying the patch.  The patch is just a quick and simple
patch, to make xc4000 works with linux 2.6.35, and I only just want to
make sure the DVB feature is up and running. I remembered that Devin
had said something about RC polling, which make the 'load' getting
high (1.00) eventhough the system proccesses are in idle or sleeping. 

In my case, the PCTV 340e dongle is cooler when it is in idle; ie, not
streaming to the host; compared to the original xc4000 driver.

One more thing is, the SNR, signal strength, ... are quite not reported
correctly. if you use 'femon -H'.

I really hope other experienced developers can take a look into the
code, and make it better compability with current kernel. :)


Thank you very much.
