Comment 18 for bug 561051

Just wanted to say that I have the exact same problem. Would work out-of-the-box on 9.10 only if the stick was already plugged when the computer was turned on. I have tried the /lib/udev/rules.d/61-option-modem-modeswitch.rules as suggested by another website and I still didn't get it work.

What I find even weirder is that I've got it working on 10.4 a couple of times, and that only happened if the stick was already plugged when the computer was turned on (this always worked on 9.10). If I remove the stick and put it back, it won't work.
