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
