I just presumed that you meant the libgphoto2/camlibs/ptp2/
directory, I got the 2.1.5 release and replaced everything
in the ptp2 directory with the CVS version (versions below)
but get the same error.

$ for i in $(find -type f -maxdepth 1 -name "*.[ch]"); do
cvs -Q status $i; done

Which patch specifically, it's a bit easier to apply a patch
to the build process rather than build the whole thing from
CVS:)

the problem is that you cann restart va_list use like the code does: 

                va_start (args, format); 
                vsnprintf (port->pc->error, sizeof (port->pc->error), 
                           _(format), args); 
                gp_logv (GP_LOG_ERROR, "gphoto2-port", format, args); 
                va_end (args); 

on some platforms (like ppc), since the internal state of args is changed. 

I committed a patch to fix this. 

The last error (0x4da / 0x2374) has the correct ids in this case. 

Is this problem then still happening? 

gphoto2 --auto-detect ?

Thats probably due to the hardware I'm running it on

# uname -srmpi
Linux 2.6.9-rc2 ppc 7447A, altivec supported PowerBook6,5

This thing upsets me:

0.378411 gphoto2-port(0): Could not find USB device
(vendor 0xfa8ddc8, product 0x200d032). Make sure this
device is connected to the computer.

The vendor and product if looks weird, and on 32bits instead
of 16

I'm going to presume that you mean /proc/bus/usb/ and say yes.
