Hi,
look at the line
InstalledAdaptors: {}
You don't have any adaptor installed. Please install at least winvideo and you cam should be detected. In order to install the adaptors run
>>supportPackageInstaller
and follow the instructions (choose the OS Generic Video Interface a.k.a winvideo adaptor later on)
