Hi Jan.....
In "WinUsb How To" doc, it says we need to make a directory of "WdfCoInstaller01005.dll" and "WinUSBCoInstaller.dll" and put it with inf file (in your app, "winusbdemo.inf"). Doc dosent mention about installing WUDFUpdate_01007.dll file.
Then manually select inf file when installing drivers. I did the same procedure, but at the end of the installation wizard says "Your device cannot be started, Not installed properly codes, codes....". Where did I miss ? Please help me Jan... If you can explain step by step (if not bother) It would be really really appreciated. Please...
