Hi! I'm a freshman here. I encountered a problem when I using the cy3684 development board. The problem is that: When I inserted the GAL(U2) into the board, PC could not recognize the board; while everything is OK, when I took out the GAL from cy3684 board. I tried 3 GALs on the board, but neither of them is OK. Can anyone know what I say, and can anyone help me to solve the problem? Thank you!!!
What about MM0 and MM1 jumper settings?. Please refer to section 2.8 of EZ-USB Development Kit User Guide (http://www.cypress.com/?docID=27825) for more information about MM0 and MM1 jumper settings.

Was it working properly on the brand new board ? Try this with a different cy3684 development board to check whether this is a board issue. What is the error and VID/PID being displayed for different MM0/MM1 settings?
