CP2104-F03-GMR device descriptor request failed

[kowshik1729]

Hi guys,

I have made a custom PCB with CP2104 USB TO UART Bridge. You can find the schematics realted to the USB below. After getting the PCB fabricated, when I plug into my computer it is showing as Device not recognized - Device Descriptor request failed. I tried lot of methods but no luck. Uninstalled the drivers using the instructions suggested in this thread . But nothing worked and i am using a Windows 10 PC. Please help me out with a correct solution.

The board is powering up properly. please someone suggest me a work-around...!! Thanks

Hi @kowshik1729 , The connection between the CP2104 and ESP01 seems looks ok, can you share a more clear picture of the Automatic IO, EN toggling Circuit. Also double-check the trace continuity with a multimeter too.

@salmanfaris oh no....the UART Bridge is not for the ESP-01. There is an ESP32-Wroom SoC, and yeah I shall share more info.

@kowshik1729 Okey, I come with conclusion from the right bottom side esp01.
