I am sorry to inform you, but current version of USB drive is very old and don't supported for years. I never tested it with latest devices and iOS. I still keep it in repository for pure historical reasons and for the inquring minds :)
Q: Will you release USB Drive 2.0?
A: I don't know, but there is a chance.
Q: Will you release source code to the public?
Hope to remove this post sometimes in the future.
