media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

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.
|
|
|
|
Some newer logitech webcams are not handled by this driver but by the
|
|
Usb Video Class driver (linux-uvc).
|
|
|
|
The built-in microphone is enabled by selecting USB Audio support.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called pwc.

Say Y here in order to have the pwc driver generate verbose debugging

A special module options 'trace' is used to control the verbosity.

This option makes USB Philips cameras register the snapshot button as
|

an input device to report button events.

If you are in doubt, say Y.
