You need the USB firmware.
Here are a couple of options if you want to use dd-wrt
Got to database here http://www.dd-wrt.com/site/support/router-database
and enter wnr3500.
Pick the 3500L and then the firmware that has USB in the filename.

You could also try Kong's version which will support USB.
It's at http://www.myopenrouter.com/download/19806/DD-WRT-Kong-Mod-USB-FTP-miniDLNA-S...
