I am trying to work on USB device. I reviewed your sample projects. I created software using them as a reference. I also designed the hardware in accordance with your design. But the computer does not recognize the device. I tried many things for the computer. I also tried different software. But it doesn't work. What is the reason of this? I shared the sample code. Can you help? Can you show me my mistake?

Have a nice day.

  • Hello. There is special equipment. My design is exactly the same as the USB design on the development boards. I couldn't try it because I didn't have a development card. I added the sample projects to my own software accordingly. I'm getting a USB device not recognized error. I don't understand the reason for this. Can you help me?
