I am a newbie to linux and have the following setup:-
(1) Ubuntu 8.04
(2) libftd2xx.so.0.4.13
(3) OpenOCD svn 983
My problem is that when I connect my Olimex JTAG debugger and run the command openocd -f openocd.cfg I get the following message
Open On-Chip Debugger 1.0 (2008-10-09-01:58) svn:983
$URL: http://svn.berlios.de/svnroot/repos/openocd/trunk/src/openocd.c $
jtag_speed: 2
Error: unable to open ftdi device: 2
Runtime error, file "command.c", line 436:
However when I run as root I get the following message

Up until an hour before this post I never had to specify root to have the last data dump show.
Many thanks in advance.
