Sierra aircard 880U and network-manager
 

Hi,
I was wondering if anyone has managed to get a sierra aircard 880U or similar card working with network-manager 0.7. I've found some things on the net saying that the aircard 880 (I'm not sure if this is the USB version - 880U - or the pcmia card - 880E - or if there is another version of this card) should work with Ubuntu 8.10, for example

My card is not detected by network manager however. Does anyone know something about this?
