CP2104-F03-GMR device descriptor request failed
-
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.
-
@kowshik1729 Did you solve the issue?
-
Not yet @salmanfaris .

@Suhailjr But I think since it's not a plug and plug play system and it will laying on the PCB for the long term, it might be fine. for me, it's similar to the Intel Edison and the PICO-IMX7 System-on-Module

@salmanfaris at last they update their design. T
What you think on the updated connector. I felt like its more fragile and high chance for corottion issue due to humidity for long term use. -

@kowshik1729 I think that might not get since the platform is not opensource! but they provided everything you need to develop a system with that.
