Hello

1.when host(PC) is connected through  USB3.0 A to FX3 the host is showing "unknown device".How to rectify this problem.

2.The 3rd pin of USB3.0 A connector is showing 3.3V in addition to 5V in 1st pin after FPGA is programmed and signals and clock are given to FX3.Why is it so?.

Hi,

If possible please swap D1 [DQ31] back with E4 [I2S_clk] and check whether the device is enumerating. I mean correct the circuit and then check for enumeration.

Thanks & regards

Abhinav
