@ChaosForged, please see the instructions at
https://github.com/Polyfun/libimobil...biledevice.txt.
You will need Visual Studio 2008.
The usbmuxd_get_device_list function in libusbmuxd\src\libusbmuxd.c would be a good starting point for debugging. Please see the Polyfun comment for a change that I added a while ago, possibly this has caused problems with IOS 8.3.
Good luck!
