I rebuild kernel.

rebuild kernel but "CONFIG_DVB_USB_RTL28XXU=m" not found

i have installed "mageia 3" to an 9 year old pc to test if driver loaded
and... succes!

on this PC there is no other hardware installed.
Is it possible that on my "better" PC this one...
01:09.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02)
with drivers,
b2c2_flexcop_pci 5750 0
b2c2_flexcop 17808 1 b2c2_flexcop_pci
s5h1420 9422 1 b2c2_flexcop

i2c_core 16933 7 cx24113,cx24123,s5h1420,nvidia,b2c2_flexcop,i2c_nforce2,isl6421
blocks the usb driver?
And...there is only "gnuradio" software...which is much too difficult to use fore me

So waiting for a better solution
bey ferdi

when things go better

edit
on the small pc, "mageia3" deleted and installed and upgraded Sabayon E17 enlightenment.

It would be nice when there come's a program for dab+ radio, as great as "kaffeine" for my dvb-s card that would be a

edit
this stick is also dvb-t tv-card not mentioned by the manufacturer!
