Installing the 3G Internet Modem is really easy. Connect HUAWEI E355 3G Surfstick with the power, run the Ubuntu installation process and once reboot, HUAWEI E355 will recognize as usb0 Ethernet connexion and work properly. I tested it with a dual boot Ubuntu/Windows 8.1. I have no problem with my VMware and VirtualBox version, so no problem with the driver. But at Windows system, I have a problem by my card, my 3G internet speed are much slower than USB network at Linux system. I don't know whether this is because of the kernel of Windows system or not.
But I really recommend that you try it, you don't need to make any problem in your computer for it, you just want to use internet on the road. With no USB power, it's perfect. I have no problem with my HUAWEI E355 3G WiFi Modem Router at Linux system. I just use USB network to reach internet at home or in the office.
Do not accept the offer of HUAWEI E355 can work with Ubuntu or Linux Mint, you need to download the 3G Surfing stick install program from the 3G surf stick website. The Ubuntu or Linux Mint would detect the HUAWEI E355 only after that you enter the setup wizard to configure it the network.
Then you could right click for install the pre-configured 3G surf stick in the desktop of Ubuntu or Linux Mint, you could even save it to USB disk, though currently the official installation will erase your system. 7211a4ac4a
