I recently bought a Macbook Pro Retina. The first day I was able to connect my Huawei e352 3G USB modem and it worked all the day. After a couple of day I needed 3G connection again, but my Macbook Pro Retina does not recognize the modem anymore. There is a micro SD card in it, and it also does not mount. The modem works with my iMac flawlessly. All the Macbook Pro Retina USB ports work flawlessly, and recognize any other devices (pen drive, blu ray writer, USB 3 external winchester).
Any ideas as to why the modem no longer functions?
