Error 0x800704b0 returned by WdfUsbTargetDeviceCreateWithParameters in UMDF v2 USB sample driver

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

How are you installing the driver on the device? If you are using "devcon install [...]" you are not using the appropriate command line, this creates a virtual device. Instead, if you are using devcon, use devcon update [...]
