MC7430 - Windows 10 unknown device

Hi,

I have installed the latest drivers for Windows 10, but one of the devices does not have a driver.

Sierra Wireless MC7430 Qualcomm Snapdragon X7 LTE-A
USB\VID_1199&PID9071&REV_006&MI_0a
USB\VID_1199&PID9071&MI_0a

Is there a link to updated drivers available to enable this device correctly?

Thanks

This looks like a bug in the driver config. Thry changing these lines:

[SWI]
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_08
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_0C

[SWI.NTamd64]
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_08
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_0C

into

[SWI]
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_08
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_0A

[SWI.NTamd64]
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_08
%gobiwwan.DeviceDesc9071%     = gobiwwan.ndi, USB\VID_1199&PID_9071&MI_0A

in /Program Files/Sierra Wireless Inc/Driver Package/Drivers/win7net/swmbbnet00.inf and then point windows there to find the driver for that device. Note that I have no idea whether this works or not. I don’t have any Windows system to test it on :wink:

FYI, MI_0A is the second RMNET function. MI_0C is the control interface of the MBIM function (if enabled). There appears to be some serious confusion in that Windows driver config…

Thanks for your reply.

I have edited the file you have listed, but the driver still does not install when pointing the driver update to the folder.

OK, that just demonstrates my lack of Windows knowledge. You need to tell Windows to use the same driver for the MI_0A interface as for the the MI_08 interface, but I don’t know how to do that.

Thanks for the update.

I’ll try to get this to work and let how know how I go.
