I always have to issue a "depmod -a" after make install. You can check
if the new modules are used afterwards with
"modinfo modname[without .ko]" and check the given path. It should
contain "updates".
Sometimes, it is necessary for me to insert a "depmod -a" even before
make install, because of missing files, which are needed by the
installation and which are created by depmod -a.


Kind regards,
Andreas
