Problem solved by removing all files and directories under /lib/modules/3.4.4-2-ARCH/kernel/drivers/media/ and repeating "make install".
Error in script "make install"? It don't removing old drivers before adding new ones?

Hi ultrakrsk. Thanks for share your solution.

Best regards.

Although this process of removing files and directories got my TBS6280 working it also killed my AverMedia AverTV Vola Green HD tuner (Linux Mint 15 kernel 3.8.0-33)
My AverMedia tuner worked fine before I installed TBS6280. I also repeated the process on another machine (Mythbuntu 12 kernel 3.8.0-33) and same thing. My AverMedia tuner worked fine before installing TBS6280 drivers and does not work afterwards.

Are we removing too much in the process described above?????

Yes and no. This is necessary to install tbs drivers.
Did you try reinstall AverMedia drivers?
Regards.

It is very unlikely that you'll be able to mix and match drivers, its usually considered a recipe for disaster.

Thanks for replies.

All that the AverMedia USB tuner required was a firmware file (dvb-usb-af9035-02.fw) to be dropped into /lib/firmware. The file is there but its not loading. Worked well until TBS6280 install

Maybe AverMedia use drivers from linux and you don't need install anything, but sure this drivers was in media folder.
Try to see what dirver is needed and then try to install these driver.

Yes, the module was there in the media folder before deletion. I tried to put the module and relevant files back in but I get the "disagrees about version of symbol" errors again.

I really think that the TBS module developers can easily answer this. Should I try compiling the kernel from source ???

"disagrees about version of symbol"

is an option in the kernel to prevent you from mixing an matching kernel modules from one kernel to another. As I stated its usually considered a really bad idea, hence why Linux doesnt want you todo it.

If you want it supported your going to have to add the support yourself. Or write an open source driver for the 6280. I dont own a 6280 but all the demods/tuners are already supported, I doubt the proprietary blob controls much.
