CodeIgniter routes problem with controller's index function - .htaccess

Question

My current development is using CodeIgniter, and when I try to pass some parameters to index function of my main controller it returns me 404 error.
http://localhost/gis/1 -> 404 ERROR
http://localhost/gis/home/1 -> 404 ERROR
Actually my route.php file has a route like this:
$route['default_controller'] = "home";
$route['home/([:num])'] = 'home/index/$1';
My .htaccess file is this (from this post to take away index.php from CI urls):
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin
ErrorDocument 404 /index.php
</IfModule>
And my config.php file:
$config['base_url'] = "http://localhost/gis";
$config['index_page'] = "";
What am I doing wrong? Thanks!

Update:
Quoting OP:
.htaccess wasn't guilty. The problem
was that my route needs to be
$route['home/(:num)'] = ... I added
both parenthesis and all works.
Rather than:
$route['home/([:num])'] = 'home/index/$1';
Try specifying it like this:
$route['home/:num'] = 'home/index/$1';
Also make sure that from application/config/routes.php, your default controller is set to home:
$route['default_controller'] = 'home';
