A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hi @Aayaan

You need to provide details about the issue. We can say F103 need a pull-up resistor of 1.5 kΩ on USB. So please describe your SW and HW environment and if possible attach the project.
