Thanks! Plugging the PSoC directly to the classmate and everything else to the USB Hub seems to work. I did not find a connection diagram either.
Warning: shorting the 3.3v on the PSoC (like with wiring mistakes) shuts it down: I/O light goes off and green light also goes off on the PSoC. Weird thing is that using 1 Analog Input port shows other 3 following. They probably need to be grounded.
