Biso007 Posted January 26, 2016 Share Posted January 26, 2016 Hi ... I have a built-in MBB modem with Vid 0x03F0 [Huawei] and Pid 0x521D. I use a legacy kext to associate it with Huawei modem kext which is successfully working to detect the device as Huawei MU736 [Pcui interface] with the 3G signal as in the attached pic. Despite having the device with the loaded kext in IOReg, yet the connection never works and always fails with error -6019 [modem doesn't respond]. Any advice or a working driver ? My laptop is HP Elitebook 840 G1 TIA HSPA.tiff Link to comment Share on other sites More sharing options...
