Device Driver - Direct Access to Endpoint 0

Archived from groups: microsoft.public.windowsxp.device_driver.dev (More info?)

Hi All,

I have made a USB functional driver and it is stacked on top of "usb bus
driver" & "usb host controller driver".
It uses the services of the lower driver(s) to access descriptors and
activate the selected interface.

We plan to use endpoint 0 (control type) for some function specific WRITE
functionality (like beep buzzer, blink error LED)

Is it possible for the functional driver to directly access endpoint 0? I
could not find any DDK calls that can allow this access.

Thanks
Ashish
