Hello,
somebody in your lab should know. 
Does it have a name? Who is its manufacturer?
Anyway, telling from the connectors, it looks as if this a usb-to-serial connection. But this might not help you since psychopy supports only the response boxes @Becca mentioned. You might want to try those (see here). Perhaps your box operates the same way as the cedrus or io labs box? Or try the keyboard-component (see here).
In case you need only two buttons, you might want to try out a gaming mouse which is usually sampled with 1000 Hz (also I am not sure whether python supports this).
Cheers Jens
