Why matlab R2014a dont want to work with my webcam?

1 view (last 30 days)
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
