How to send a control message to USB device without writing driver?

Hi all,

I am really new to the driver development and I'm feeling so hard to write a driver after scan through the example in the WDK...

Currently I am using the libusb filter's function to send control message to a device. I am trying to put the USB device into TEST_MODE by sending a SET_FEATURE request to the usb device.

It works fine for most of the driver but I face some failure on the WPD class on device which has MTP. When I turn on the filter on the WPD device it just fail to load.

So, is the current windows usb driver exposed any API for user to send a control message like I specify above? (I want to put the device in test mode) If yes, how do I do it and can anyone point out the reference for me?

If the answer is not, what can I do? Writing another filter driver for the WPD device? How do I start?

Thanks in advance. Hoping to get some answers.
