The OpenLib( and ExecLib commands can be used to access usb8x functions from BASIC programs. Input and output is passed through a list in the Ans variable. On input, the first element of the list holds the function number of the command to execute and the remaining elements hold input values. On output, the first element holds the success/error status (where 0 is success) and the remaining elements may hold output data values. See the information page on individual functions to determine its function number and input/output values.
Note: Versions of usb8x prior to 0.10 require that the input list be seven elements long. Elements that are not part of the defined input are ignored.
Example code to quit unless a USB device is connected:
