Parameters

EnableUSBHub

When false (the box is not checked), this parameter keeps any processing from happening. When true (the box is checked), the program runs as it should.

COMPort

This is where the active COM port is defined. This COM Port is the location that the USB Hub is connected to. This information can be found on Device Manager, where it should list the COM port that is being used by the USB. If incorrect, the program will not run.

ToggleUSBs

This parameter defines the trigger expressions to turn off the USB. Each row label contains the USB number it corresponds to. Each input must be a BCI Expression. In the example shown in the figures, StimulusCode is the used expression. When the condition expressed in each row is met, that USB will be turned off.

States

Port1 - Port6

1 bit states that relay when a USB port is on or off. There are 6 separate state variables, one for each USB. 1 for on, 0 for off. The default state is that they are on.
