Right-o. I did a search for the Sprint Novatel Wireless Ovation u720, since I just bought one and wanted to get it working with Slack, and found a few scraps here and there but nothing essential. Well come to find out that Sprint lo-and-behold has a manual.
It's is a 2mb DL.
Now it does not say anything about Slackware. In fact it only throws around names like Ubuntu, Knoppix, Fedora, OpenSuse, etc. However it says that you must have Kernel 2.6.x.x and be running KPPP.
Also the card has to be activated on a WIN32 system.
And there are some known limitations:
The big one is that the card speed is limited to the speed of the Generic USB driver around 500kbps.
Anyway, the link is above. I will be posting to this as I get it working, which should be in the next couple days. However, if by chance someone reading this post has actually got it working in Slackware 11.0 or Slamd64 11.0 let me know. I don't care about other distros as the majority of them do not follow the same directory configs as Slack and Slam.
