If you have usbutils installed, /usr/sbin/lsusb -v will give you info like

Bus 001 Device 004: ID 046d:08f0 Logitech, Inc. QuickCam Messenger
Device Descriptor:
idVendor 0x046d Logitech, Inc.
idProduct 0x08f0 QuickCam Messenger
<much snipped>

Using the vendor/product id in a google search such as "046d:08f0 linux",
will return sites showing what other people have done, to get the particular
webcam working. Note that the solutions vary, depending on the kernel version.

P.S. According to:

the driver family (ASIC) for the QuickCam Communicate Deluxe is
"SPCA527", and the Linux driver is "uvcvideo".

The question, therefore is: does gspca provide the spca527
uvcvideo driver?
(Assuming the kernel version matches - see earlier posting).

My solution because I use xterm for my terminals

xterm*saveLines: 4096
in ~/.Xresources
and/or ~/.Xdefaults

Yes, I've installed gspca (matched with kernel).

I've done 'modprobe -f gspca'

'ls /dev/video' returns: "/dev/video@"

Connected the QuickCam to a USB port, and: nothing happens...

Have I missed something, or done the wrong thing?

Problem with that is that it produces pages of output, such
that scrollimg back to the top doesn't go far enough, i.e. I
can't see the start of the output!

Haven't come across this before. How does one avoid losing the
early lines of output?

To capture all stuff sent to the console, including
error messages:

command -options 2>$1 > junk

That put standard error into the same place
as standard output and puts both into file junk
in the current directory.

Cheers!

Running a google search on "046d:0992 linux" leads to
which indicates this is a v4l2 device.

Remove any modules you've already added, to try and get the device working.

Run "modprobe -v uvcvideo", which should also load v4l2_common, and if
not already loaded, videodev, v4l1_compat, compat_ioctl32 and usbcore.

Then connect the webcam, and check /var/log/syslog, to see if it
is recognized.

The webcam will only work with software that supports v4l2.
