I have a PCB with ESP32-Wroom32 module and CP2012N is used as USB to UART converter for Firmware upload via Arduino IDE. Issue is when I connect USB of PCB to my PC then my Task manager is not showing any port therefor i am unable to upload code in it. I am attaching the schematic of PCB. Can anyone tell me what can be possible issue in the design? I have tried many things like adding latest driver for CP2102N in my PC but I am still not able to figure out that issue is in PCB or in PC. I have even tried my laptop aswell but same issue is there, No COM port is shown in task manager
R20 is grounded. It should be connected to VDD. The CP2102N is being held in reset. I would also recommend using a 10k as your pull resistor.
As @Jens mentions SUSPENDb is an output. It should not be connected to ground. It can cause a dead short if the pin pulls high. Disconnect, if you are not using it.
