Q: gphoto2 does not find my camera. What shall I do?
A: First try to run "gphoto2 --list-ports" and look whether the ports
you want to use are listed.
Then try to run "gphoto2 --auto-detect" and look whether the camera
is detected.
If you gphoto2 cannot access the USB device, you have to set up
hotplugging correctly. See gphoto2.txt for details.
========================================================================
Q: I get the error message
*** Error ('Could not claim the USB device') ***
Could not claim interface 0 (Operation not permitted). Make sure no
other program or kernel module (i.e. dc2xx) is using the device and
you have read/write access to the device.
What can I do to make it work?
A: You have to set up the permissions on your USB device correctly.
For Linux, this is described in the file named gphoto2.txt in
your gphoto2 documentation directory (named doc/ in the source tree).

Q: My Canon PowerShot G1/Pro 90 IS doesn't work with gphoto2 when using
the AC adapter. What should I do?
A: This is a known bug which we cannot fix since none of the active
gphoto2 developers own one of these cameras. Your alternatives are as
follows :
Fix it and send us a patch.
Donate a G1 to one of the active Canon driver developers.
Run the camera on battery instead of the AC adapter.
There is some more info regarding this at
http://krixor.xy.org/fredrik/gp/canon-g1-ac-problem/
good luck.

Q: I have a special problem with CameraXYZ. Where can I find information
about it?
A: You can look into the README file of your driver <driver>. It is
located in camlibs/<driver>/ in your source tree.
========================================================================
Q: I run Linux 2.4.x and I can't get USB to work at all. I keep getting
kernel: usb_control/bulk_msg: timeout
kernel: usbdevfs: USBDEVFS_BULK failed dev 3 ep 0x81 len 64 ret -110
How can I make USB work?
A: No idea. Sometimes it works and sometimes it doesn't. If you know a
solution, please let us know.
