Subject: Where should I ask about USB Target code?
Date: Fri, 25 Apr 2014 10:32:01 -0400	[thread overview]
Message-ID: <535A71E1.7030804@GlueLogix.com> (raw)

I am developing a USB print capture device based on Gumstix Overo (TI 
OMAP) and the Gadget printer driver in Linaro 3.5.0 distribution.  It 
looks like the distributed gadget driver may not be responding to USB 
Setup messages.  I have used printk to verify that my data is correct 
when function composite_setup returns, but it does not appear on my 
Beagle 12 USB analyzer.  I have not changed anything lower down than 
composite.c.  Reading the code in usb/core is not helping much.  I 
really want to trace the call stack from composite_setup back to the 
silicon, but cannot find where the .setup method of the composite driver 
is called.

So my newbie question is, where do I go to find people who are into this 
part of the kernel and talk it over with them?

Thanks,
Larry
