Hello, I sent the following message to the linux-usb mailing list and
they suggested I try here. I'm trying to get a "Dazzle Video Capture
USB V1.0" video capture card working on a Linux device but it doesn't
look like the chip set is supported yet. I believe this card is the
next version of the Pinnacle VC100 capture card that worked with the
em28xx kernel module. The hardware vendor that sold the card says that
this device has an Empia 2980 chip set in it so I'm inquiring about
support for that chip set. I'm just wondering about the best approach
for getting the new chip supported in the kernel. Is this something
the
em28xx maintainers would naturally address in time or can I assist in
getting this into the kernel? Here's dmesg from the Debian box I'm
working on: [ 3198.920619] usb 3-1: new high-speed USB device number 5

ask
this question please point me in the right direction. Thanks, Keith
The em28xx is indeed the dedicated driver for this device, but it's
hard
to say how much work would be necessary to add support for it.
We currently don't support any em29xx chip yet, but in theory it is
just
an extended em28xx device.
Whatever that means when it comes to the low level stuff... ;)
What's the best route to get support for this chip added then? Should I
start working on a patch myself or will this just happen during the
course of development of the em28xx module? I'm a developer but haven't
done any kernel hacking so this would likely be a steep learning curve
for me.

Frank
