A quick 'grep' shows that the camera is supported:
./libgphoto2/camlibs/canon/doc/Protocol.xml:            <row><entry>PowerShot G5</entry><entry>02-May-03</entry><entry>yes</entry></row>
./libgphoto2/camlibs/canon/doc/Protocol.xml:	  as the product ID, which is correct for the PowerShot G5.</para>
./libgphoto2/camlibs/canon/canon.c:        {"Canon:PowerShot G5 (normal mode)", CANON_CLASS_5,     0x04A9, 0x3085, CAP_SUP, SL_MOVIE_LARGE, SL_THUMB, SL_PICTURE, NULL},
./libgphoto2/camlibs/ptp2/library.c:	{"Canon:PowerShot G5 (PTP mode)",       0x04a9, 0x3085, PTPBUG_DELETE_SENDS_EVENT|PTP_CAP|PTP_CAP_PREVIEW},

Can you tell me which mode (normal/PTP) did you use ? 

Can you set '--camera MODEL' and see what happens ? It 
will necessary to use '--port' too. 

"--list-cameras" (List supported camera models.) and
"--list-ports" (List supported port devices) can be
a help.
