Asus Merlin - Unsupported USB modem

[Datashuttle]

Have a Sierra Wireless modem MC7455 connected USB. I need to install the drivers for this card. I expect to compile the driver as a first step since it's unsupported. Has anyone done that, and if so, can you point me in the right direction so I don't have to reinvent the wheel?

Thanks up front.
