I've been trying to get my Raspberry Pi to work with one of two TV Cards that I have available on me. Unfortunately I live in Hong Kong where due to the digital broadcast standard, leaves me with few choices of devices. Neither of which seem to want to play ball.

For obvious reasons, both are USB. I have "determined" that one uses a RTL2836U chipset. Whilst the other is using a LME 2510C with a Maxim 2165E tuner and 8G75-A1 demoduator.

I had been focusing my efforts to efforts on the RTL2836U and I just compiled some drivers (with the VID/PID added) and Linux seemed to load the modules, but then unloaded it due to an error.

Any help would be appreciated.

The kernel version would also help. And the distribution. –  schaiba Feb 28 '13 at 19:40
    
@schaiba Rasbian 3.6.11 –  Aron Feb 28 '13 at 19:41

As far as I can tell, your error stems from the version incompatibility between the running kernel and the kernel version you're building the modules against. Check uname -r against your tree.

As apt-get doesn't seem to have a kernel headers package for 3.6.11 I had to download the kernel source and rebuild them. Although I read somewhere I only need to 'make modules' rather than a full make. If I need to full on replace the kernel I'd likely need to cross compile...The pi is pretty darn slow. What do you suggest? –  Aron Feb 28 '13 at 19:58
    
If you search for kernel headers with aptitude, what results do you get? –  schaiba Feb 28 '13 at 20:52
    
So you have kernel 3.6.x, but as Raspbian is Wheezy-based, it has 3.2.x . This creates the question: how did you get the 3.6.x kernel and what do you have in /etc/apt/sources.list? –  schaiba Feb 28 '13 at 21:40
    
The kernel was built into the Raspbmc image I started with (a Raspbian with XBMC slipped in), I downloaded the sources from github.com/raspberrypi/linux, the master 'branch' looks to be 3.6.11. –  Aron Mar 1 '13 at 2:10
    
I just found this thread on another forum. Will try it out this weekend. forum.stmlabs.com/showthread.php?tid=6780 But thanks for the help so far. I will report my progress either way. –  Aron Mar 1 '13 at 2:17
