One note about the Sierra modem: Some 3g/4g cards including this one, need a powered USB hub for consistent service. As Sebkinne has noted elsewhere, the USB port of the Pineapple does not provide enough amperage to support higher current devices. The 313U works for a short time and then the USB port dies until reboot unless I am running this from a powered USB hub and then it stays online till I power down.

I do not know if everything here is set perfectly but I do know this configuration works: *0f3d:68aa*) echo "Sierra Aircard 313u detected.
