I have a E362 mobile usb cell stick from Telus. I connected it and executed sudo modprobe usbserial vendor=0x12d1 product=0x1505 to load the according drivers. That gives me /dev/ttyUSB0 link! Then I went ahead and created a Mobile Broadband connection wth the network manager but the drop down where I am supposed to select the device is disabled. I however can keep going and create the connection but it wouldn't let me select the device and hence, after creation, the network manager never offers me to connect to it.

Why not? How can I select my correct /dev/ttyUSB0 device?
