For 3G devices this could be a number of things. If the device simply isn't seen by NM, that means that ModemManager didn't successfully probe the device. So we need to look for it there. If this happens when the device disconnects, it could be that the device's firmware is crashing and its dropping off the USB bus. That's odd and indicates firmware problems, some of which we can work around in ModemManager. Other times the device is just screwed and needs a firmware update. If the device isn't recognized at *boot* time, that could indicate either kernel problems, device problems, or possibly udev issues. When the device isn't found, lets get some 'dmesg' output from the kernel to see if the device is actually getting loaded correctly. Also see if the device's ports are present in /dev/.
