Further comments: there is apparently a driver floating around this list
for supporting PTP through the gadgetfs. How does this work relate
to that, and why can't you use gadgetfs?

Second: after looking at this, I think that atleast the part of functionality
called "OS descriptor" should be in the kernel and not in userspace,
is the OS descriptor the reason to why you want to expose EP0 to
userspace, or are you using this for other things in the MTP stack?

Yours,
Linus Walleij
