From: anshul makkar on 30 Apr 2010 23:46 Hi, As per the documentation available (a single PDF file) to implement USBOIP we have to implement a virtual host controller driver . - Virtual Host control driver will be equivalent to USB Host Controller driver and will be responsible for handling of URBs. - USBs will be converted to USB/IP packets and sent to remote machine - At remote machine another application will extract URBs from USB/IP packets and submit them to local USB drivers. Now according to earlier postings and other documentation , Microsoft does not provide any support / documentation for writing host controller driver. I may have to do lot of reverse enginnering to decipher the functionality of USB Host Controller driver. So just wondering whethe the above design approach will be correct, considering lack of support/documentation from Microsoft. Is there any other design approach that can be suitable ? Please share your views and experiences. -- Thanks Anshul Makkar justkernel.com anshul_makkar(a)justkernel.com

If we knew what is your Real Problem, we could suggest alternatives. Of course, unless you are tasked exactly to create a virtual USB host controller. Regards, -- pa

You need not spam this group with these same incessant inquiries as you've already posted on NTDEV. Do your research and search the archives of both groups, this has been covered many times. No one is going to tell you how to do it, it's never going to work totally correctly, and MSFT is not going to help you either. You're pretty much on your own ... (which again you have been told many times).
