Device not detected or use by other application
Go to 'Windows Task Manager' (ctrl+alt+del) and click the 'processes' tab and (if possible) stop only devices affected and retry. Be careful not to stop devices/drivers required by windows or any application in use otherwise windows/application will stop working.
If a device is not in use and still not detected or is wrongly reported, get the latest drivers and install them first. You may check device settings and make changes as required. If all else fails and you have the original software, try re-installing it after a proper uninstall.
