CP2104-F03-GMR device descriptor request failed
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 .
What are objects?
Jeff Goodell: Would you explain, in simple terms, exactly what object-oriented software is?
Steve Jobs: Objects are like people. They’re living, breathing things that have knowledge inside them about how to do things and have memory inside them so they can remember things. And rather than interacting with them at a very low level, you interact with them at a very high level of abstraction, like we’re doing right here.
Here’s an example: If I’m your laundry object, you can give me your dirty clothes and send me a message that says, “Can you get my clothes laundered, please.” I happen to know where the best laundry place in San Francisco is. And I speak English, and I have dollars in my pockets. So I go out and hail a taxicab and tell the driver to take me to this place in San Francisco. I go get your clothes laundered, I jump back in the cab, I get back here. I give you your clean clothes and say, “Here are your clean clothes.”
You have no idea how I did that. You have no knowledge of the laundry place. Maybe you speak French, and you can’t even hail a taxi. You can’t pay for one, you don’t have dollars in your pocket. Yet I knew how to do all of that. And you didn’t have to know any of it. All that complexity was hidden inside of me, and we were able to interact at a very high level of abstraction. That’s what objects are. They encapsulate complexity, and the interfaces to that complexity are high level.
This webinar is focussing on learning Git VCS, a distributed version control system for tracking changes during practical software development.
We will be exploring the usage of various git commands, plugins/extensions and branching-models based on real-world contexts.
The session is targetting absolute beginners with minimum or no experience with git, But a mindset to optimize and improve work efficiency and productivity by learning and exploring new tool-chains and strategies is a must!
