nRF52 PCA10040 no uart console output with micro USB connected

[BigJim]

problem description:

hi, I just got a PCA10040 development board with which I plan to learn about nrf connect SDK.

so I try the common BLE peripheral demo,but I 've met a frustrating puzzle that  I cannot get a single line of  uart log from Putty with the  USB wire straightly plugging between  micro USB slot on PCA10040 and PC。

more details:

1.I've set Macro "CONFIG_UART_CONSOLE = y"（I can see RTT log if setting "CONFIG_RTT_CONSOLE = y"）

2.I assume the UART log can come out from micro USB, is this right or I need some wiring .

Hi thanks for your keep-on focus.I want to tell you that I got another PCA10040,with which the problem I issuing doesn't happen.

so I can probably draw a  conclusion that it is only caused by the hardward related to the Serial to USB.
