Does anyone know what the %DeviceId% parameter passed to StreamingDeviceSetup in the .inf command "rundll32.exe streamci.sll,StreamingDeviceSetup %DeviceId%..." should be in the case of a hardware device?I see that for SW\SomeGUID (swenum) devices it is the GUID of the device. It seems that passing a hardware device ID string causes StreamingDeviceSetup to (silently) fail. --------------------------------- Do you Yahoo!? Yahoo!
