I have two laptops running ubuntu 12.04 with the latest updates. One is a gateway ID79C and the other is an ASUS SM56CM. All I needed to do to get connected on the gateway was to add

usbserial
option

to /etc/modules.

I did the same thing on the asus but it seems not to be recognizing and adding the option lines in dmesg.

Relevant dmesg output:

The only difference that I can see is that the asus is using xhci_hcd (usb 3.0) vs ehci_hcd(usb 2.0) on the gateway.

I have also tried manually switching with usb_modeswitch but it says it can't find previous drivers.

Any help would be greatly appreciated.

To add some more information: lsmod | grep option option 30115 0 usb_wwan 20491 1 option usbserial 47077 2 option,usb_wwan option and usbserial are present –  br8kpoint Feb 8 '13 at 19:47

I got it working on the ASUS by going into the bios and disabling xhci. SO it is definitely something wrong with the xhci functionality in conjunction with usb_modeswitch/option. So no usb 3.0 love for me until this issue is sorted out :(
