Winusb Driver Problem !

[ranabasu]

Hi Jan...

This question is about Winusb+ C# application and firmware found from your page. When I attach my device to pc, it asks to install drivers. I manually browse and select inf folder and device starts to install the driver, then it says "The file WinusbCoInstaller.dll on my install disk is is needed".

>>Where can i find this file ?  Where to install it ?

>> Does Winusb driver support XP sp3 and higher versions ?

Thank You

I made a derectory which includes,

WinUSBCoInstaller.dll
WUDFUpdate_01007.dll
WdfCoInstaller01007.dll

3 dll files and name the directory as i386, and it's automatically recognized by driver installation wizard. After copy them to the system32 folder, finally wizard says "Cannot start this device, re install drivers, code 18"
do i need to install entire wdk environment ? pls help me....................

You need the driver, winusb.dll

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...
