[Lula] understanding the Linux USB subsytem

[Vineeth, Balan (IE10)]

Hi all,  

             

I am totally new to Linux as well as USB , (have gone through the USB
spec) .Documentation for the USB subsystem seems to be very hard to get.


 All information I get tells me how to write a device driver whereas I
want to know how the actual USB core works?  

 

As of now I am deciphering the source code which is strenuous task.
(URL:
http://www.gelato.unsw.edu.au/lxr/source/drivers/usb/core/?a=i386

            

            I found an open source resource at
http://www.srcdoc.com/linux_2.2.26/  which gives  function level  call
graphs .            

Is something similar available for the Linux 2.6 kernel? Can any body
direct me to some better documentation?.

 

 

Regards,

vineeth
