Hi,

I'm looking at developing a UMDF v2 driver for a USB device. To get started I followed the tutorial at the link below, "How to write your first USB client driver", which uses the UMDF v2 USB driver template from Visual Studio.

I'm able to build a driver with this method. But when starting it, I see "This device cannot start. (Code 10)" in Device Manager.

Activating WPP tracing, I see that the call to WdfUsbTargetDeviceCreateWithParameters fails with error 0x800704b0

How can I get more information about this error code to know what the cause might be?

Thanks,

Romain
