[Gphoto-user] Can't get hotplug to run the usbcam script

[James B. H. <jh...@vi...>]

Hi list.

As the subject says - can't seem to get hotplug to run the usbcam
script.

Environment:  linux-2.6.8-rc1-mm1; hotplug-2004_01_05; libgphoto2 and
gphoto2-2.1.4; camera is an HP Photosmart 735.

I know everything hardware-wise works, since I had this working a
couple months ago.  I've traced through all the behavior.  When
I turn the camera on, I get:

Jul 25 03:02:18 bassett kernel: ohci_hcd 0000:00:07.4: wakeup
Jul 25 03:02:18 bassett kernel: usb 1-2: new full speed USB device using address 11
Jul 25 03:02:19 bassett kernel: usb 1-2: Product: hp photosmart 735
Jul 25 03:02:19 bassett kernel: usb 1-2: Manufacturer: Hewlett-Packard
Jul 25 03:02:19 bassett usb.agent[2812]: ... no modules for USB product 3f0/4002/100

in /var/log/messages.  So the USB business is working.

I've also put echo's in the various hotplug scripts to trace the flow,
and just about everything seems to be working right there, EXCEPT I never
get an entry into the usbcam script.  This is more or less confirmed
by the permissions on the camera device in /proc/bus/usb/001:

-rw-r--r--    1 root     root           43 Jul 25 01:03 001
-rw-r--r--    1 root     root           50 Jul 25 03:02 011

My /etc/hotplug/usb/usbcam script is the usbcam.group script with
the only change being that I've set the group to "users", which is the
user group on my box.

My /etc/hotplug/usb.usermap and /etc/hotplug/usb/usbcam.usermap files
are identical except that the usb.usermap file has the first line being
the example that is there from the hotplug installation; the rest of
the lines are the output of the print-usb-usermap.

I've followed the manual setup instructions to the letter, best that I
can tell.

The output from gphoto2 --summary when run as root is:

*** Error ***              
An error occurred in the io-library ('Bad parameters'): Could not find USB device (vendor 0x3f0, product 0x6a02). Make sure this device is connected to the computer.
*** Error (-2: 'Bad parameters') ***       

and:

jhiller@bassett:~$ gphoto2 --summary
                                                                               
*** Error ***              
Could not detect any camera
*** Error (-105: 'Unknown model') ***       

For debugging messages, please use the --debug option.
Debugging messages may help finding a solution to your problem.
If you intend to send any error or debug messages to the gphoto
developer mailing list <gph...@li...>, please run
gphoto2 as follows:

when run as a regular user.

I'll not put the huge --debug output up on the list until it's needed.

Any help that could be offered would be bigly appreciated - I'm on hour 10
on this matter :-(

thx,
jbh
