LED & Switch Circuit is here.
EZ-USB circuit is on website here.

7 segments LED are drived by SN74LS04 because EZ-USB is running 3.3V and LED drive voltage is 5V.
AN2131 Voh(Min)=2.4V (@Vcc=3.0V)    74LS04   Vih(Min)=2.0V

AN2131 can input 5V signal as swtches input.
AN2131  Vih=2.0V(Min) to 5.25V(Max)
