i am using a cypress Ez-USB FX2 chip for my project.The Hardware is already complete .But after assembling the finished PCB it is not working.I checked for everything
proper reset is given
We checked the 24MHz crystal it is also working perfectly .3.3V Vcc is also there.But the PC fails to detect the chip as well as the Cypress USB manager.
I am novice with USB and This Board was designed by some other person who has left the organisation .Can anyone Guide me on howto debug this Hardware Problem.
Thanks in Advance
