Hi guys,

I am a newbie to USB HID device control.

I'm having a problem with getting an access to endpoint 0.
My device has 3 endpoints 0, 1 and 3.
I see the devices only for ep1 and 3 in Device manager of Windows Control Pannel, and access them.
I don't see the ep0 device from the list.

Is there anyway to get an access to ep0 and Read/Write from c# application?

please help me out.

Thanks for the comment.
But I already read it in that link.
It doesn't say about control transfer which is to control ep0.

When I search the device with the function,
The paths for ep1 and ep3 are detected but the path of ep0 is not detected.

Is assume that is why I can't creat the file handle and Read/Write.
