Hello:
I recently acquired a Kensington camera model 67016, and have been
trying to get it fired up on Linux. Alas, I keep hitting a wall:
p4:provinsd@ve6cta:/usr/local/src/gqcam-0.9 2$ ./gqcam
/dev/video: No such device
I installed the latest "gtk" libraries.
I installed the se401 module and can "modprobe" it up:
Module Size Used by
se401 14464 0 (unused)
videodev 4800 0 [se401]
usbcore 50848 0 [se401]
I have ensured that the BIOS has USB enabled:
Bus 0, device 4, function 2:
USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 1).
IRQ 9.
Master Capable. Latency=32.
I/O at 0xb400 [0xb41f].
but I see nothing in /proc/bus/usb when the camera is plugged in.
I made sure that the recommended devices were in /dev:
p3:provinsd@ve6cta:/dev 14$ l video*
lrwxrwxrwx 1 root root 6 Dec 24 14:28 video -> video0
crw-rw-rw- 1 root root 81, 0 Dec 24 14:18 video0
crw-rw-rw- 1 root root 81, 1 Dec 24 14:18 video1
I added "radio. vtx and vbi" devices as well, although I have none of
these. I also linked bttv to video0, although it wasn't clear why this
was required.
Speculating that I needed some sort of "scanning" device enabled (that
was the closest device that I could see that existed in the "/dev/usb"
directory), I added:
p3:provinsd@ve6cta:/dev 17$ l usb
total 0
lrwxrwxrwx 1 root root 8 Dec 30 12:46 scanner -> scanner0
crw-rw-rw- 1 root root 180, 48 Dec 30 12:45 scanner0
crw-rw-rw- 1 root root 180, 49 Dec 30 12:45 scanner1
It didn't help.
I did notice that in "/etc/modules.conf" there was the line:
alias char-major-81 bttv
Being unsure, I left it as was.
An "strace ./gqcam", results (in part) with:
open("/dev/video", O_RDWR) = -1 ENOSYS (Function not implemented)
open("/dev/video", O_RDWR) = -1 ENOSYS (Function not implemented)
open("/dev/video", O_RDWR) = -1 ENODEV (No such device)
I have read recent messages on the list, written by others
employing this, or similar cameras, but see nothing similar.
Kernel is:
Linux ve6cta 2.4.9 #1 Sun Dec 30 13:14:42 MST 2001 i686 unknown
with the following (relevant?) options set:
CONFIG_USB=m
CONFIG_USB_DEBUG=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_UHCI=m
CONFIG_USB_STORAGE=m
CONFIG_USB_SCANNER=m
CONFIG_USB_SE401=m
CONFIG_VIDEO_DEV=m
CONFIG_VIDEO_PROC_FS=y
CONFIG_I2C_PARPORT=m
You may be wondering if the camera is functional at all. Well, I had
it running briefly on a Win '98 system, with the Kensington software,
but it was frustratingly slow, so I killed that OS and moved up in the
world. As I had a second camera handy (I plan to give it to an
acquaintance, as a gift), I tried it too, but "no dice", as my father
used to say.
If you have any suggestions, I would be grateful to hear from you.
I'm sure that I've missed something, but cannot see what it is.
Regards,
Dean
