I had to do some searching for a USB modem that works in Linux, but I found one.
I got one recently and it works great. I used kppp and I had to increase the pppd timeout limit but other than that (and figuring out how to set it up) there weren't any problems.
$30 isn't exactly scorching hot but the only other ones I could find that I know for a fact work in Linux were much more expensive. I thought someone else might be looking for one, so I thought I would post. It is also pretty small so it easily fits in a laptop bag.
