If your SSID_wlan0="HBF" then your config file should be called
wlancfg-HBF.

Are you getting any useful messages in /var/log/messages ?

try running ifconfig

try running iwlist to see if the card has found any networks.

Getting these cards setup the first time can be a bit tricky, so don't
panic.

It does work with udev & NetworkManager if you prefer a GUI to set
things up. You'll have to check your distro to see if NetworkManager is
installed & enabled.
