Since at least Jaunty, I've tried to get my wife's 3G USB modem to work on Ubuntu, always with the same result - instant, complete system freeze.
I've tried installing`wvdial and usb-modeswitch, I've read tons of documentation but it gets quite disjointed from one release to the next, nothing works. I can't run lsusb because the system hangs immediately.
I'm using Lucid and it's a Rogers "Rocket Stick" (in Canada)
