Say Y or M here if you want to use one of these Philips & OEM
webcams:
* Philips PCA645, PCA646
* Philips PCVC675, PCVC680, PCVC690
* Philips PCVC720/40, PCVC730, PCVC740, PCVC750
* Askey VC010
* Logitech QuickCam Pro 3000, 4000, 'Zoom', 'Notebook Pro'
and 'Orbit'/'Sphere'
* Samsung MPC-C10, MPC-C30
* Creative Webcam 5, Pro Ex
* SOTEC Afina Eye
* Visionite VCS-UC300, VCS-UM100
The PCA635, PCVC665 and PCVC720/20 are not supported by this driver
and never will be, but the 665 and 720/20 are supported by other
drivers.
This driver has an optional plugin (called PWCX), which is
distributed as a binary module only. It contains code that allow you
to use higher resolutions and framerates but may not be distributed
as source. But even without this plugin you can these cams for most
applications.
See <file:Documentation/usb/philips.txt> for more information and
installation instructions.
The built-in microphone is enabled by selecting USB Audio support.
This driver uses the Video For Linux API. You must say Y or M to
"Video For Linux" (under Character Devices) to use this driver.
Information on this API and pointers to "v4l" programs may be found
at <file:Documentation/video4linux/API.html>.
To compile this driver as a module, choose M here: the
module will be called pwc.
