Windows Logo Compatible Testing

Dear All,

I am working with the user mode USB echo_driver sample provided in the source kit.

Since the test device is also of USB type, after building the driver I modified details in the INF file to suit my requirements and installed the driver.

In the Device Manager the driver is shown under seperate class called WUDF Sample. In order to make it to appear under generic USB controller sections, I modified the ClassGUID and DriverClsID values in the INF file. I got these values by seeing INF file of another USB device which was already installed.

When I try to install the driver again, the newhardware wizard gives the subjected warning message.

Can anyone provide a pointer about how the WUDF sample INF file got those ClassGUID and DriverClsID values.

Regards,
Uday Bhaskar.
