Usb port access

Mon, 05/09/2011 - 11:51 — Monkey

When I run rawlog-grabber application I get the following output in the terminal

monkey@monkey-HP-Pavilion-dv6700-Notebook-PC:~/Desktop/Project Development$ rawlog-grabber kinect.ini

rawlog-grabber - Part of the MRPT
MRPT C++ Library: MRPT 0.9.4 - BUILD DATE May 9 2011
-------------------------------------------------------------------

Output rawlog filename: ./data_kinect_2011-05-09_16h40m18s.rawlog
External image storage: ./data_kinect_2011-05-09_16h40m18s_Images

=============== MRPT EXCEPTION =============

Press any key to exit program

Waiting for all threads to close...

I'm not sure how to provide access to the usb ports???

Any Advice would be much appreciated

You have not read the platform specific comments part of http://reference.mrpt.org/svn/classmrpt_1_1hwdrivers_1_1_c_kinect.html.

Linux: You'll need root privileges to access Kinect. Or, install MRPT/scripts/51-kinect.rules in /etc/udev/rules.d/ to allow access to all users.
