Make sure you have kernel-source, kernel-syms, C++, gcc and make installed & that kernel-source & kernel-syms match your running kernel (uname -a) – if not do an update.
Because you have been messing around, do “make clean” prior to starting over.
You have to remove the previous driver at the proper place & modprobe the new driver; then you also have to select it on the card’s config tab in Yast and reboot.
should work:)
