Hello everyone, I'm still new to gnu/linux (why not linux/gnu? an idea has no name imo :) ) and must have dodged my way around my webcam during manual kernel configuration / compilation. I never use it, but it would be nice to not have to get my age-old camera working and pray that it would be recognized as a mass storage device. Regardless, here is the output from lsusb (not very descriptive, I know :/ )

Code:

...
Bus 001 Device 004: ID 19ff:0102 Dynex 1.3MP Webcam
Bus 001 Device 003: ...


and here is the output of dmesg when I plug it in.
Code:

[14573.412397] usb 1-6.1: adding 1-6.1:1.3 (config #1, interface 3)


Are there any utilities to get a more detailed insight into the device recognition lshw goes into (besides lshw)? Any help would be awesome. I'd like to make a webcam-based multi-touch screen some day (hopefully soon!), so this is a great way to dive into the difficulties. Thanks in advance!

Spewface ...

A quick search suggests its uvc based so the driver would be uvcvideo (USB_VIDEO_CLASS), its under:

Device Drivers => Multimedia support => Media USB Adapters

With the driver enabled you should be able to use mplayer, or cheese, and test it ... something like:

Code:
% mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 -fps 20 -vo xv

HTH & best ... khay
