The current driver is (1) open source (GPL) and (2) in the 2.5 kernel, see drivers/usb/misc/speedtch.c, so you should have no trouble getting it. The only thing that Alcatel kept closed source was the firmware loader, and even that has an open source replacement (modem_run, see speedtouch.sf.net). As for "what else would be required to get this working?", well that's a pretty vague question. The obvious answer is: specs for the modem. Specs for the firmware too! Actually, all you really need is a driver for windows, since it is fairly easy to monitor windows USB traffic and reverse engineer the protocol. > I have already explained to them that I would only lead the project to get > this done and that it would only be in my free time and that the end driver > would be open sourced. The speedtouch modems are very simple. You just send it a bunch of ATM cells to transmit; it sends you a bunch of ATM cells for reception. And that's it. The other USB interfaces are for loading the firmware and monitoring the line state. Of course you get this simple behaviour because that's how the firmware sets things up. With very different firmware, the driver might need to change a lot.
