Hi,  
  
I'm trying to use the USB-1408FS for digital output. I know that only the 1208FS and the 1608FS have been tested. In the past, I used my own mex-files using the MCC libraries under windows. But I want to run psychtoolbox under linux, and need to use PsychHID, as MCC doesn't provide their libraries for linux.  
  
The device is detected by PsychHID:  
PsychHID('Devices') returns 6 devices, 4 of them belonging to the 1408FS, as expected. I assigned the last device to daq.  
err = DaqBlinkLED(daq) returns err.n = 0 and blinks the LED on the 1408FS.  
internally, it runs:  
err = PsychHID('SetReport',daq,2,64,uint(64)).   
This shows that I can communicate with the DAQ via PsychHID.  
  
Now the problem:  
I want to set the values on port 0:  
port = 0; data = 255; err = DaqDOut(daq,port,data)  
No error, but the bits on the digital out are not changed.  
internally, DaqDOut runs:  
reportID = 2;  
TheReport = uint8([0 port data]);  
err = PsychHID('SetReport',daq,2,reportID,TheReport).   
This should work for the 1208FS. But no error and no digital out change on 1408FS.  
  
Ideas how I could modify the entries to PsychHID to get the digital out to change on the 1408FS? Or where I find the information so I can figure out how to set reoportID and TheReport?  
  
Thanks, Till Hartmann

The problem is identical on windows and linux:  
Windows 7 64bit, Matlab 2013a, PsychtoolboxVersion 3.0.11, libusb-1.0.dll  
Linux Ubuntu 14.04, Matlab 2016a, PsychtoolboxVersion 3.0.12

Try to get daq = DaqFind; Our code should control the 1408-FS, but it is important to use device interface #0. Maybe your way of getting daq connects to the wrong interface.
