My computer does not get connected through USB.

Normally when the Qbus System Manager III SW is installed, the USB driver is installed automatically, but if this is not the case your computer will tell you, once you connect to the controller, that it is having trouble installing the USB device. When this happens please click on that message and select to install the driver from a list or specific location (search: C:\Program Files (x86)\Qbus\CTD USB driver if you have left the program to install in the default location and if not select the location were you have installed the program and this specific folder) . This way the system should connect properly.
