Mini stream Driver for LogiTech Camera

Hi all,
I am reposting this message again.
I am writing a windowsXP mini stream driver for USB LogiTech camera.
Following are specification of the Logitech QuickCam Home
Sensor type - CCD
Maximum True Resolution - 352 x 288
supports USBCAMD library.
The device needs some Vendor specific commands from driver for setting
up the device.
I dont know the Vendor commands supported by LogiTech camera.
If anybody knows the command set or the way to get these commands pls
reply me back.
Thanx in advance,

Rafi Maniyar
