Chosing the right Linux "USB Gadget" API and Driver Framework

Chosing the right Linux "USB Gadget" API and Driver Framework

[Robert Schwebel]

I'm currently working on support for the USB gadget controller inside
the Intel PXA25x XScale processor. David Brownell has recently published
a new USB gadget API which was discussed on linux-usb-devel and which
seems to be a good starting point.

As there is at least one other API (by Belcarra, former Lineo code) I'm
wondering what Greg's and Linus' position concerning the new USB gadget
API is. A comment from your side would be welcome. 

Cheers,
Robert

I've looked at both apis, and think the one from David looks much better
than the old Lineo code (don't know if that has been updated in a long
time, I might not be aware of newer developments with that code.)

So, barring any unforseen pushes from the ex-Lineo developers I expect
David's code to make it into the main kernel tree eventually.

Hope this helps,
