It works well on Linux before. I can see ttyUSB0, ttyUSB1 and ttyUSB2 after install GobiSerial driver. I also can see qcqmi0 after install GobiNet driver. But all of them disappear now after I try to plug-in my modules to Windows8 host and dial-up LTE with SkyLight connection manager.

As we still rely on the Serial ports for development (Not to mention the QMI interface), I was wondering if there are any Windows Guru’s out there that might know of a fix to prevent Windows from doing this? W… I suggest you trying with linux machine.
