Thanks to Harry, Colin, Peter and Ian for your advice. I respond to each in turn. Harry: I will follow up on the Huawei Wireless USB modem. For the present I intend to pursue Telstra for an answer, rather than let them off the hook. I believe that it would be a simple task for them to laod a PC with Ubuntu and test the modem, after which they could let Linux users have instructions on using the modem with a Linux OS. Telstra have told me that they have used Ubuntu but without clarification.
Colin: the lsusb command in Terminal lists the modem as 'ID 0f3d:68aa Airprime, Incorporated'. So its presence is recognised. the lsmod command has no match for 'UHCI' or anything similar. Vaguely similar are 'usbhid Used by 0' and 'hid Used by 1 usbhid'. Peter: I have consulted the lists you recommended but there is no direct reference to the 360U modem. I am still looking up the links to see if there are other clues. From the remarks in the lists it seems that the Ubuntu network connection manager is being used correctly and should show the assigned connection name in the menu (which it is not doing now). Ian: I am using the APN: telstra.bigpond. I believe that it is the correct plan name. However I would like to see the screen grab of your settings so please email. Thank you. Lastly to all: If I am able, with help, to get this modem working on Ubuntu 12.04 I will certainly post the result on this Mailing List.
