This patch includes the first version of some support
for autoconfiguring gadget drivers. Later versions may
be able to offload some logic into controller drivers,
but this API looks like it'll suffice to get rid of
compile-time configuration for simple drivers.
Basically drivers just call

This patch makes "Gadget Zero" autoconfigure itself, getting rid
of most of the controller-specific conditional compilation.
(Whoops, I forgot an sa1100-specific quirk.)
Notable changes were:
- Use the new config buffer utilities. This simplifies code
and also makes it easy to handle the Supe

This patch makes the necessary updates to the bluetty, cdc-acm, and usblp
class drivers for the new interface/altsetting paradigm. The changes are
quite small.
Unfortunately, the audio and usb-midi drivers are in much worse shape.
They will require more in-depth hacking, to come later.

Hello,
I need to achieve telnet on top of PPP on top of USB
serial between PC and my device. I have a driver based
on linux USB serial driver. It can talk with minicom
on RedHat to transfer characters.
Then, how to make PPP run on top of USB serial to
achieve telnet?
Any guildline is appreciated
