// The order of layering the hooks is important here because of deps
// 1. Fix low level libusb thing with init
// 2. Introduce the shim layer to allow adding fakedevs required for forther software emulation
// 3. Turn the ITG 2 piuio kernel hack calls into normal piuio ctrl transfer calls
// 4. Exit module to allow exiting the game with test + service
// 5. Software emulation layer for piuio
//
// For example, the kernel hack layer takes care of removing that, so software
// emulation code doesn't have to bother with that edge case. Furthermore, it allows you
// to use the game with real hardware without any additional software emulation layers
// that have to detour to real hardware again
