BACKGROUND : Most of these data-card devices now have two logical devices inside one physical device.
(a) usb-storage-device This contains/serves the driver software that poor windoze users must install (but not required for Ubuntu/Linux). (b) usb-modem-device. This is invariably the "ttyUSB0" communciation device required by Ubuntu/Linux. SUSPECTED PROBLEM : The problem (often) is that the "storage-device" of these data-cards seems to interfere with Ubuntu/Linux ability to automagically detect, configure or utilise the "usb-modem-device" on the data-card. SOLUTION : Assuming that the storage device is the issue, then it can be resolved by installing and activating usb-modeswitch. Please google for instructions to install and use usb-modeswitch on Ubuntu. It is fairly simple and often a one-time process. Package is installed via synaptic-package-manager. I have had successes on two Ubuntu support calls with this approach, and thereafter do this as default for all data-cards where I know it has some storage. (most of the current EVDO and 3G usb devices have the driver software on that storage). Good luck.
