Hi Jonathan,

thanks for your reply,

you r right. our device is also support usb video class. but my
question is related to pc side driver for usb camera (approx usb host
driver which communicates with application that shows the video to
user).

Could you clarify my first post questions?

Thanks in Advance.

Regards - D.

My device is based on BlackFin processor. I don't know exactly it
supports usb video class spec.

If it supports USB video class, then you don't need to write a driver
at all. That's what we've been saying.

BlackFin is just a generic microcontroller. It doesn't know anything about
video. The behavior of the device (and the spec compliance) is entirely
determined by the way you program the microcontroller.

Are you writing the BlackFin code as well?

Three people have answered your questions. If your device is USB Video
Class compliant, then YOU DO NOT WRITE A DRIVER AT ALL. No software is
needed. All of the major operating systems (including Windows) have a
driver built-in that will do everything that is required. You just plug it
in and start a capture application.

Hi

thanks for your reply,

We get one usb video driver from 3rd party which is working fine in
xp,vista,win 7 - 32 bit OS.
but it is not working in 64 bit platform even though it is compiled in
64 bit build environment of wdk.

Is the same source code of usb video driver able to work in 64 bit
environment?

any guys knows about usb video driver porting for mac os?

B'coz i searched in mac os and google, i can' find any sample code for
mac os. is there any development environment for device driver
development in mac os like wdk?

thanks in advance.

Regards - D.
