This requires root access (or more accurately, CAP_SYS_MODULE capabilities). That's why your insmod fails. > sunil@ubuntu:~/test/drive$ sudo modprobe helloworld > FATAL: Module helloworld not found. > This is a different action from 'insmod helloworld.ko'. modprobe tries to load the module from /lib/modules/`uname -r`. It's slightly more convenient because it will also load all modules this one depends on. In this case this fails because your module doesn't actually live in /lib/modules/.... Try sudo insmod helloworld.ko instead.
