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?
dude, can't you read ? gadgetfs prevents us from combining into a composite
gadget. We went throught that already. Please follow the thread before
commenting.
Yeah sorry, I'm trying to catch up and miss some pieces here and there.
I'm mainly reading it from the MTP side of things.
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?
OS descriptor is MS specific crap, it's not on the USB-IF mtp spec and most
like MS has some patent on that.
...so I read you like it's not going to be supported with the proposed
solution?
I think that if you want you gadget to work with older Windowses,
you simply have to support this.
The device can simply fall back to PTP mode on older Windows.
