I don't have a powershot, but my Canon EOS 60D works fine.... Hang on this
is 32 bit too. Let me try on another machine. Yup, works for me on 64bit
machine as well. Thunar shows: gphoto2://[usb:001,006]/DCIM/100CANON/
where my pictures are. Entangle also is able to connect on both machines
and set various things on the camera and then trigger a shutter event for
teathered operation. The only thing I have to watch out for is that the
camera shuts off after a time out. In my case just touching any control
brings it back... I toughed the menu button. Best thing is to plug in
while the camera is off and turn power on while thunar is open. You should
see the camera show up in devices and can click on it.

I have automounting turned off as is default. If you have it turned on you
might try turning it off.

I am not using any external USB hub and don't have any other USB devices
in use on either machine. I chose a mother board that has PS2 mouse/KB
because USB mice are known for causing audio xruns in some cases. It would
seem it is not a kernel problem in any case, but the possibility of some
driver issue is there. I have found the USB ports on the back work better
for me than those on the front for some things (USB hard drive in my
case), but I used the front port this time with no problem.

Those are my guesses and experiences. I don't know if any of them will help.
