Hi Mario and Ben,
  

We having a problem in the Luck lab with the DAQ and it's preventing us from using PTB while doing EEG research. &nbsp; We're running El Capitan and 3.0.13. &nbsp;The DAQ used to work on PTB 3.0.12. &nbsp;  
  
I did some invetsigating. &nbsp;The main problem is the DaqDeviceIndex() function is broken. &nbsp;It returns nothing. &nbsp;Upon further inspection of the program, I can see that PsychHID() shows our Daq device (FS-USB1208-FS). &nbsp;But the DaqDeviceIndex() function doesn't return the indexes like it's supposed to.

  

Mario:&nbsp;&nbsp;If you could advise me about what might be going wrong, I'll fix the bug and send you an updated version of the code.

  

Thanks in advance.

  

-Nick
