DRIVERS HELP

[XmodX]

ok, im a little bit newb, but i know a good bit, enough to get Linux running on my xbox. But, heres my situation: Im getting ready to leave on a 2 week boat trip down the east coast. I have limited space on my 28' boat, and i want to use the xbox for everything--jukebox, pc with internet, etc. I have been planning on using a pocket pc with my sprint phone for an internet connection. but thats a pain in the ass. I found a new usb cable for my sprint, that will let me use it as a usb modem on a pc. The company's website has drivers for windows and i downloaded them and it works great, its even faster than i expected. But how can i get or write or have someone help me write a driver for Linux on the xbox? I have 2 usb ports installed on my xbox, 160gb maxtor, and all the extras. It would be so cool to have usb modem on my boat! if not, im gonna have to take a pc and monitor, which sucks, as space is very limited on a boat. the xbox fits fine right on top of my 13" tv and would make a great all purpose machine. Please help.

No one can even make a suggestion? i guess i would need to know how to write dll's to make a driver. doesnt matter at this point. I just bought a laptop.

WOW! You must be an incredible programmer if you invented DLLs for Linux! </sarcasm> Anyways, a driver is not something one can write on a weekend.

yeah, i know. that was stupid. im not a linux programmer, so excuse my ignorance. but there must be an equivalent for linux. i give up.

I was just joking there, but seriously, a driver isn't an easy thing to write. Even something as simple as a usb light driver is rather challanging. Here is an example of that driver (in the kernel 2.6 tree):
