When the LogTag Analyzer Installer determines that the USB drivers need to be updated while one or more USB interface cradles are connected, it will prompt the user to disconnect them.
You will only need to remove your LogTag USB equipment, having other USB devices like Mouse, keyboard or memory sticks connected during this process is OK. Once you have disconnected the USB interface cradles, the NEXT button in the installer will allow you to continue with the installation.
However, if the USB drivers do not successfully unload, because for example the Analyzer software is running, when you click the NEXT button, the installation software will prompt you to disconnect the USB interface cradles again. To force the USB drivers to unload, please follow the manual removal steps described in the next question.
