Why matlab R2014a dont want to work with my webcam?

I tried three different cameras, only one was connected with every try and always a same result.

>> imaqhwinfo

ans =

    InstalledAdaptors: {'winvideo'}
        MATLABVersion: '8.3 (R2014a)'
          ToolboxName: 'Image Acquisition To...'
       ToolboxVersion: '4.7 (R2014a)'

>> imaqhwinfo('winvideo',1)

ans =

             DefaultFormat: 'RGB24_320x240'
       DeviceFileSupported: 0
                DeviceName: 'Logitech QuickC...'
                  DeviceID: 1
     VideoInputConstructor: 'videoinput('win...'
    VideoDeviceConstructor: 'imaq.VideoDevic...'
          SupportedFormats: {1x15 cell}

>> obj = videoinput('winvideo',1)

Error using videoinput (line 391) winvideo: Image acquisition device is not accessible. No such interface supported Make sure no other objects or applications are accessing the same device.

Best way to solve this ---> if the usb webcam doesnt wanna install winvideo but you just have webcam, so you absolutely should choose : Image Acquisition Toolbox Support Package for "OS Generic Video Interface". This is the answer.

This Image Acquisition is suit running on > Matlab2014
