+	   * Philips PCA645, PCA646
+	   * Philips PCVC675, PCVC680, PCVC690

+	   * 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.
+
+	  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

+	default y
+	depends on USB_PWC && (USB_PWC=INPUT || INPUT=y)
