[Lula] understanding the Linux USB subsytem

[Vineeth, Balan (IE10)]

Thanks Dan.

 

I am an engineering student doing my final year project at Honeywell. I
am trying to get a hold of the Linux USBD so as to implement the same
for a Philips controller (ISP 1761). (The Linux stack is too big) . I
have already visited the web sites u have mentioned , but did not find
information up to the level that I wanted . The codeViz tool is
something new and I will certainly try it out. Will it work in windows
XP with Cygwin installed?

 

Thanks for the help

Regards

vineeth

Have you tried http://www.csn.ul.ie/~mel/projects/codeviz/ ?

 

Also, have you read

http://www.linux-usb.org/

http://lxr.linux.no/source/Documentation/usb/

?

 

By the way, what are you working on?  We might be able

to give better advice if we knew.
