+Zoran 364xx based USB webcam module version 0.72
+site: http://royale.zerezo.com/zr364xx/
+mail: royale@zerezo.com
+
+introduction:
+This brings support under Linux for the Aiptek PocketDV 3300 in webcam mode.
+If you just want to get on your PC the pictures and movies on the camera, you should use the usb-storage module instead.
+The driver works with several other cameras in webcam mode (see the list below).
+Maybe this code can work for other JPEG/USB cams based on the Coach chips from Zoran?
+Possible chipsets are : ZR36430 (ZR36430BGC) and maybe ZR36431, ZR36440, ZR36442...
+You can try the experience changing the vendor/product ID values (look at the source code).
+You can get these values by looking at /var/log/messages when you plug your camera, or by typing : cat /proc/bus/usb/devices.
+If you manage to use your cam with this code, you can send me a mail (royale@zerezo.com) with the name of your cam and a patch if needed.
+This is a beta release of the driver.
+Since version 0.70, this driver is only compatible with V4L2 API and 2.6.x kernels.
+If you need V4L1 or 2.4x kernels support, please use an older version, but the code is not maintained anymore.
+Good luck!
+
+install:
+In order to use this driver, you must compile it with your kernel.
+Location: Device Drivers -> Multimedia devices -> Video For Linux -> Video Capture Adapters -> V4L USB devices
+
+usage:
+modprobe zr364xx debug=X mode=Y
+ - debug      : set to 1 to enable verbose debug messages
+ - mode       : 0 = 320x240, 1 = 160x120, 2 = 640x480
+You can then use the camera with V4L2 compatible applications, for example Ekiga.
+To capture a single image, try this: dd if=/dev/video0 of=test.jpg bs=1 count=1
