After my kid's Macbook Pro retina self update (currently showing as ver 10.10.3), the Huawei
3G USB dongle can't work anymore & the OSX will prompt with some sort of message to
upgrade the driver?
The huawei mobile broadband USB dongle modem is model E173 (CE0682 O2)
As I'm no OSX user, kindly guide me step by step/click by click to fix this
