Good day all,
I am hoping someone can shed some light onto the problem I'm having
hooking up my Kodak DC280 Zoom through USB under Linux. I have
configured (from what I understand correctly) USB under kernel version
2.4.17. This included setting up a mount in my /etc/fstab as
none /proc/bus/usb usbdevfs defaults 0 0
creating the following devices in /dev/usb (I know, I shouldn't have
set it world writeable, but it doesn't work even as root)
sorbet:/dev/usb# ls -al
total 24
drwxr-xr-x 2 root root 4096 Feb 23 16:30 .
drwxr-xr-x 6 root root 20480 Mar 1 08:01 ..
crw-rw-rw- 1 root root 180, 80 Feb 23 16:04 dc2xx0
crw-rw-rw- 1 root root 180, 81 Feb 23 16:30 dc2xx1
crw-rw-rw- 1 root root 180, 82 Feb 23 16:30 dc2xx2
crw-rw-rw- 1 root root 180, 83 Feb 23 16:30 dc2xx3
crw-rw-rw- 1 root root 180, 84 Feb 23 16:30 dc2xx4
crw-rw-rw- 1 root root 180, 85 Feb 23 16:30 dc2xx5
installed version 0.1.4 of libusb and dded the following lines to
me /etc/modules file (for Debian 3.0)
usbcore
usb-uhci
scanner
dc2xx
When I do an lsmod I get
Module Size Used by Not tainted
dc2xx 3232 0 (unused)
scanner 8448 0
usb-uhci 20964 0 (unused)
usbcore 48064 1 [dc2xx scanner usb-uhci]
I have no problems getting my HP ScanJet 6300C working under
Linux through the USB interface, but my Kodak DC280 Zoom is a different
story. A cat of my /proc/bus/usb/devices gives me

It seems clear that I can probe the digital camera, unfortunately,
I then run
gphoto2 --camera "Kodak DC280" --port usb: --get-all-images
and I get the message
Status: Initializing 'Kodak DC280'...
*** Error ('Could not claim the USB device') ***
The following message is the last internal error message.
This message may currently still be unrelated to the real error:
Could not claim interface 0 (Device or resource busy). Make sure no other program or
kernel module (i.e. dcxxx) is using the device and you have read/write access to the
device.
For debugging messages, please use the --debug option.
Why could it not claim the USB device? Have I missed a step somewhere
in setting it up where my digital camera wouldn't work but my scanner
will work?
Cheers!
Richard..
