Usb host controller driver

NTDEV
1

Hi All,

I need write host controller driver for Windows XP. This is ehci
compatible hardware in general, but will not work with standard
Microsoft drivers. I have an experience with writing usb controllers
driver in general and with windows drivers as well. My problem is that i
need to interface with standard usbd.sys in order to make my hardware to
be recognized as an additional host controller and from brief search i
did not find interface description ( callbacks structures … ) on MSDN
or web. As far as i know hardware vendors is implementing such driver so
usbd interface can be reached some way.
The driver will be used for hardware testing (host controller) and will
not be distributed.
Can somebody (probably from Microsoft) bring some lights on this issue ?

Thanks in advance,
Ilya Lifshits.

The interface to usbd (and its replacement usbport) is not published
and, in general, not given out. If you want to pursue this further,
contact Fred Bhesania, xxxxx@microsoft.com, the USB program manager.
