What else must I do to set up a new custom module? I am defining my first custom module and cannot get Drupal to see it.

What I have done:


Created a subdirectory with module name at sites/all/modules/custom/mymodulename. The name is just letters, nno spaces underscores or dashes.
Added two files mymodulename.info &amp; mymodulename.module.
mymodulename.info contains: name = mymodulename and includes a description, package = Other, and core = 7.x.
ran update.php
flushed caches
reloaded admin/modules page
module is not listed???


I suspect that I somehow let Drupal know this is my first attempt and it is just messing with me! How can I appease it?
Check for spelling mistakes, because you seem to have everything you need for it to be listed.
