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 doesn't work with gphoto2. What should I do?
|
|
|
|
A: This is a known bug which is being worked on. In the mean time, run
|
|
the camera on battery instead of the AC adapter.

|

How can I make USB work?

|
