% "DeviceIndex" is a small integer, the array index specifying which HID
% device in the array returned by PsychHID('Devices') is interface 0
% of the desired USB-1208FS box.
% See also Daq, DaqFunctions, DaqPins, DaqTest, PsychHIDTest.

% 4/15/05 dgp Wrote it.
% 12/20/07 mpr tested it on 1608FS and then made input argument optional
% 1/10/08 mpr swept through trying to improve consistency across Daq
% functions
% 5/22/08 mk Add (untested!) support for USB-1024LS box.
% 5/23/08 mk Add caching for HID device list.
% Perform internal caching of list of HID devices in 'TheDevices'
% to speedup call:
persistent TheDevices;
if isempty(TheDevices)
TheDevices = PsychHIDDAQS;
end
