Option Icon 225

The Option Icon 225 is a usb key to connect to internet via a mobile network.

ZeroCD
When you plug in the key, it is recognized as a usb storage key containing drivers for Windows and Mac OS (this functionality is known as ZeroCD). Obviously this is not good, you need to switch the key from the ZeroCD mode to the modem mode. That can be done with a small utility called ozerocdoff.

Kernel configuration
The driver for the modem is hso, it is included in the kernel since 2.6.27

Installation
ozerocdoff is not yet in portage, but there is bug 253869 in bugzilla with ebuild. You cound place it to your local overlay.

Alternativly, you cound install it manually.

Manual install
Get the latest version from pharscape.org

Using this command everytime you plug-in the key would be quite tiresome, so you can had a udev rule to do it for you.

Configuration
The last thing needed is a connection script.

Modify the variables APN/USER/PASS/PIN to fit your configuration and run the script

NetworkManager
The device works with a very recent version of Networkmanager from the rbu overlay (http://overlays.gentoo.org/dev/rbu/browser/overlay/net-misc). The bug concerning this is here (http://bugs.gentoo.org/show_bug.cgi?id=257661).

The Networkmanager version from the overlay has to be compiled with the "modemmanager" USE flag enabled. After that any Networkmanager frontend can be used to configure the connection.
