My Stimtracker stopped working. I have been using it with SuperLab 4.5.3 to conduct a classical conditioning experiment and until now it has been functioning perfectly. Today, when I tried running the experiment, the following message appeared on the screen "Superlab couldn´t find a ´StimTracker´connected to this computer for sending out Digital Output events´.
At first I though the problem was that I may have forgotten the stimtracker turned off, but to my surprise it was already on (I could see the led on). This message kept appearing even though both photocells are working too (they are responsive to stimulus). I have tried connecting the usb cable in other usb ports of my computer, but it didn´t work. The problem does not seem to be related to the usb ports because evething else (mouse and keypad) are able to function normally when connected to any usb ports.
What is the problem with my stimtracker? I would appreciate some help.
