Re: [gphoto-devel] gphoto2 on OS X 10.4/Tiger

[Gregory D. <du...@ci...>]

In order to use photo2 on OS X (i.e. Apple mac) you need to kill off  
any programs that are
already listening on the USB port (probably for camera connections).   
The error
below: "Could not claim the USB" is symptomatic of having some other  
USB application owning the port.

Typical OS X installations include some kind of PTP application (or  
maybe it was part of a
Canon camera package I installed).  To kill it, you might also have  
to become super-user using
the "sudo" or "su" commands.  If you are installing gphoto2 I assume  
you know how to
do this, but for the record note that on fresh OS X installations the  
super-user must be enabled
using the netinfo utility.
