Description of problem:
gphoto can not access my Canon Powershot S400.
Works fine in version gphoto2-2.1.4-2 but fails on gphoto2-2.1.4-5.
Error dialog from gtkam states:
Could not list folders in '/'.
An error occured in the io-library ('Bad parameters'): Could not find
USB device (vendor 0x4a9, product 0x3075). Make sure this device is
connected to the computer.

Version-Release number of selected component (if applicable):
gphoto2-2.1.4-5

How reproducible:
Everytime on my computer
Worked on callon's w/ gphoto2-2.1.4-2.1
Worked on Nalin's w/ gphoto2-2.1.4-2
upgraded to gphoto2-2.1.4-5 and it stopped working

Steps to Reproduce:
1. Plug in camera and turn it on
2. Open gtkam (as root since there seems to be an unrelated
permissions problem)
3. Select menu item Camera/Add Camera...
4. Select correct camera model
5. Hit ok

Actual results:
Error dialog pops up

Expected results:
Be able to download my pictures

Additional info:
Could this have something to do with dave's hotplug patch?
