This idea was inspired by:
https://github.com/PointCloudLibrary/mobile/blob/master/3rdparty/android/patches/libusb.patch
The whole thing is re-written from scratch but the idea came from there,
and its a way simpler way of getting a system-opened fd to the right
place than patching every call in the stack to pass a fd down.
