RTL2832U driver modded for Linux kernel 3.0.0

Hello, I'm Thomas, a Frontend Developer from Munich, Germany.

I've been working as a software developer for over 10 years writing software for desktop, mobile and the web. I'm focused on frontend web development with TypeScript for big single page applications. One of my major interests is the architecture of such applications and especially the tooling necessary to develop at scale.

dvb-realtek-rtl2832u-2.2.2-10tuner-mod_kernel-3.0.0's Issues

Merge support for r320t

Dvb-t usb dongles mounting realtek rtl2832u and Rafael Micro r820t are garnering increasing success due to them being even cheaper than the e4000-based, dismissed ones they are replacing, being good at doing that, and having been recently supported by rtl-sdr project.

I have one; however, using it to watch dvb-t (I am in Europa) turned out to be difficult.
The only way that worked: downgrade my linux kernel to 2.6.33.3, and compiling these sources:

https://groups.google.com/d/msg/ultra-cheap-sdr/QiIo7834sLI/7YpqSRnYud4J

which forced me to using an older commit of v4l (mercurial df33bbd60225), and to comment out all references to rtl2832u_rc_keys_map_table.

In a word: it works, but the situation is disappointing.
The task now is importing the existing code as from above into a current kernel, possibly drawing code from rtl-sdr, hoping they cleaned the r820t part a bit.

Advice on who to ask else is also welcome.
Thanks!

PS: Be aware: identification of these cheap dongles can be hard. In my case, lsusb returned 0bda:2838, which is the same as other ones having e4000 or fc0012, as ezcap EzTV646. Even the appearance can be misleading: there are e4000 looking exactly the same.

No device under /dev

Hello!

I have compiled the driver under Sabayon 10 (3.5.3), with modprobe I have loaded into the memory the driver, but no device name (dev/dvb/adapter0) under the device tree!

I made a udev rule and the device name is showing under /dev, but I can't use it with VLC!

Can you tell something me about it!

Thx, Zsolt

Linux 3.5

Hi,

I'm forced to run the 3.5 kernel and X.org packages from the Ubuntu xorg-edgers ppa[1] due to issues with my graphics card[2]. Unfortunately the rtl2832u driver stops working when I'm switching to the 3.5 kernel. It compiles and loads, but it doesn't produce any output after that, although I've set the debug level to 7. Any Ideas?

Best wishes
Christophe

How do I determine that it IS working?

I have successfully compiled and installed the modules. No problem there.

In fact, it's been running (uptime-wise) for a couple of days now; which I take shows that the drivers are stable enough.

But, there's another kind of problem: When I run w_scan (see below for more detailed report), I get "ERROR: Sorry - i couldn't get any working frequency/transponder. Nothing to scan!!"

I have checked everything I can. I have checked the antenna cable too --it works OK on a TV.

Yet, there's no output on the PC, and it's driving me up the wall.

Is there another/better way to test that this card is working?
