I recommend a 1 kOhm pull up resistor on the reset pin, other than that the schematic looks ok.
Does using an EVK work as expected on your computer? Are you using the latest drivers? When you plug the board in, does the CP2104 appear in the list of usb devices you get when you use the "lsusb" command?

Hi Joe,
Thank for your answer.
In fact, i have corrected the PCB with 4.3K Ohm pull up resistor on pin 9. Do you think than the problem came from this mistakes ?
What is the use of an EVK in my case ? i don't understand.
About the drivers, i am using OS debian 9.8 which is update. I can read WSTK usb port over minicom usually.
When i am plugging the USB i have this on lsusb :
-- Bus 001 Device 110: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light.

CP2104 serial to UART
Hi,
I am using attached diagramme to convert serial (TX and RX of BGM13P22) signal to USB.
It i cannot read my log throw the ttyUSB0 when the custom PCB is connected in my PC.
Is there a mistakes on schema ?
Than you,
