Greetings,  
  
Are there any functions in any version of psychtoolbox that enable   
matlab to locate and/or recognize a device plugged into a usb port  
(mac or pc)? We are attempting to sync an eye-tracker with a   
program running in matlab and the info stream from the eye-tracker   
would be coming in through USB preferrably though possibly serial.   
Any information on this subject would be greatly appreciated.  
  
thank you,  
ck
