Hmm, one of my comments was that the ".inf" file (and docs) should
go into Documentation/usb so that it's more accessible!

I've done about the same testing, against a 2.6 host; the OTG bits
work correctly. Since you signed-off on this, I'll assume it's OK that
I merge this to my "gadget-2.6" tree so it gets (maybe) a bit more
exposure/testing.
Quick comments:
- Hmm, you copied/pasted the "ISO 8859/1" comment, that
should actually say "UTF-8"! My bad.
- What would you think about changing the ACM logic so that
the driver normally initializes as ACM? Many operating
systems have ACM drivers already. If the module parameter
is explicitly set to "false", or an "interrupt" endpoint can't be
found, then it'd come up in non-ACM mode.
- Hmm, the embedded environment I was using expects devfs
to set up the /dev files; but that's not supported by this driver.
(It's the only gadget driver where devfs would make sense.)

That sounds familiar. Are you using the latest net2280 code from the
gadget-2.6 tree? The EVB boards handle reset a bit differently from the
RDK boards, and I thought a fix had been merged to address that.
(If not, [EMAIL PROTECTED] should be able to help ... Alex Sanks
ought to recall the detals.)
