thats okay -
let me clarify everything you did
1. you downloaded the driver emu10k1-v0.19a.tar.bz2 from sourceforge, this was saved in directory /root
2. you did a tar -jxf emu10k1-v0.19a.tar.bz2
3. you did a cd emu10k1-v0.19a
4. you did a make
5. you did a make install
6. you did a modprobe emu10k1 and that is when the errors occured
Am i missing anything?
when you type ls -l /usr/src/ what comes up?
