On custom board, VDDUSB_CAP connected 10uF and 0.1uF capacitors.
(On SABRE-SD, VDDUSB_CAP connected 10uF [C627] and 0.22uF [C633] capacitors.)
Because the discharge time of VDD_USB_CAP is too late, there is possibility of remaining the 0.6V voltage at the next Power ON.
Is there a problem in this voltage (0.6V)?
If the voltage cause the problem, could you tell me the workaround?
