[AG-TECH] Webcams for Linux

G'day all

Just to throw in my 2 cents worth.

 I have used a couple of older types of webcams, a dLink DSB-C300 and a
Cisco (not sure of make and model) which is a Logitech camera rebadged,
USB cameras that simply just work.  I find I have to install drivers
under windows, but they just plug in and work under Linux (Fedora) :-)

The dLink DSB-C300 produces a poor image, but the other USB produces
pretty good quality for a USB camera.

Anyway, hope you find these comments useful.

UCL vic from the SUMOVER SVN repository has V4L2 support, as does AG
The new UCL vic from SVN will even work with V4L2 webcams that only

For the Fedora 7 AccessGrid 2.4 & 3.0.2 RPMs, I've retro-fitted the V4L2
support from AG 3.1.

Sorry I don't have any recommendations, just some comments.

The UVC driver was having lots of issues with timeouts (and I'm not
about with just vic, but even a verbose 'lsusb' will produce half a
timeouts). See the UVC linux driver mailing list archives for more
I'm not sure if the timeout issues have been fixed. Some of the
patches posted on the list worked great on some PCs but not others.

I would prefer the 2nd revisions of the UVC Logitech webcams (the ones
the works with Vista printed on the packaging) as apparently they
uncompressed video at the lower resolutions, unlike the 1st generation
that provided MJPEG. Unfortunately the 2nd generation of Logitech UVC
webcams are more prone to the UVC driver timeout issues.

I've had success with the cheap Microsoft Xbox360 Live webcam, it's
the cheapest UVC webcam on the market. Unfortunately I didn't have
on all PCs with it, due to the timeout issue mentioned above.
