How do I write an OSX device driver for a USB WiMax modem?

Question

I am planing to spend few days a week writing a driver for a Greenpacket USB WiMax modem. Greenpacket only provides Windows driver with it and as I am fond of Linux and Mac I feel very bad not having driver for them.

I have experience writing C++ programs so I think it won't be hard for me. Even I like C++ programming very much. I have never written drivers but I know some concepts. I have PDF of the device specification from the company's website.

I would like to ask if I can write driver with that provided specifications? If yes what would be my starting point assuming I would like to write it for MAC first and then Linux. I am reading this article right now but your experiences would be of great help.

Answer 1

The product specifications sheet does not provide enough data to write a device driver. You are going to need low-level information about how to speak with the WiMax device via USB. You are probably also way out of your depth of you think a product sheet is enough information to write a device driver.
