CY7C65632-28 Oscillator only oscilates when device is in reset.
I have 20 new prototype boards using the CY7C65632-28. A couple of the board came up and the USB works properly. On most the USB Hub doesn't work. The 12MHz oscillator will only run when the hub is held in reset. The HUB is configured as self powered and the gang input is connected to ground with a 100K resistor. Reset uses the recommended reset from Cypress. 10K to 5V and 47K in parallel with 1uF to ground.
Anybody had similar experience?
