I originally posted this article on my old personal blog around this time last year for Ubuntu 9.1 as I was having problems getting my O2 mobile Broadband E1752 Dongle to work. I certainly upgraded to Ubuntu 10.04, which I had heard solved the problem but I still couldn’t get it to work, so looked up my own old tutorial and it worked.

Ok here is how I got my o2 E1752 Modem working in Ubuntu.

Put your sim in your dongle and plug into a usb port. For the E1752 model the network manger applet will not pop up unlike other dongles. The reason for this is somthing to do with the device also acting as a storage device So what you need to do is use usb_modeswitch which can be downloaded in a .deb file here (found it somewhere can’t remember) which makes it easier to install. Then as root user find the file usb_modeswitch.conf and add the below code to the bottom of the file ( big thanks to cocoa’s post here for that code) ######################################################## # Huawei E1752 # # Contributor: DefaultVendor= 0x12d1 DefaultProduct= 0x1446 TargetVendor= 0x12d1 TargetProduct= 0x1001 MessageEndpoint= 0x01 MessageContent= "55534243000000000000000000000011060000000000000000000000000000" Then go into your network manger and go to moible broadband tab. Click add and it will start a wizard, your country should be already Ireland Select your pay plan, mines o2 contract, then click next and then finish Then click on the new connect you just made and edit it. There should be default stuff in there, leave all that, but in the pin field place your own pin and click apply Once this is all done, open a terminal window and run this command sudo usb_modeswitch It will prompt for your system password, once the script does its thing the network manager icon should start doing somthing if not left click on it and select the connection you setup Now you should be connected to the world wide web





Well I hope that helps someone, because I know I was searching for ages trying to get it working. I only got it working yesterday evening and I still haven’t got around to getting use_modeswitch to run on startup so everytime you restart your computer you will have to run the sudo usb_modeswitch command in the terminal.
