Hello,
Sorry I sent the previous message on my Android phone while
standing on a windswept beach and holding my hat on my head! Here is
the message without that handicap and more descriptive!

Thanks for the reply. Sorry to ask such a basic question but here
goes - if the drivers on my system will not work with the code form
the hg tree can I access the git tree and obtain the branch for the
kernel I am using. I can then modify the code and load the uvc
drivers in and use those? I'm investigating the bandwidth used by
some webcams I have and have been looking at some of the work done to
access multiple webcams - I'm playing with UBS2.0 and USB3.0 to see
what happens but I would like to be able to edit the uvc code to put
in some logging (at first) and just want to get started with something
(i.e. print Hello World out when setting the bandwidth).
Any help on this is greatly appreciated.

Thanks again.
Regards,
Neil
