Hello team,
Good day,
I am having USB Disconnect Issue with my custom board based on STM32F303 Device, configured as USB HID in Firmware with Full speed. Schematics attached here with.
It is Self-Powered board and no VBUS Detection implemented, Currently.
USB Cable from HOST PC will always plugged into our Board and upon power on it detects the Board as HID device successfully. and communication works fine as well.
Issue is : During real-time communication windows HID Function finds device disconnected. PC application is based on MFC VC++.
We are not sure if it is beacuse of Noise or Immidiate VBUS Detection ?
Regards,
Bsuthar

Schematic is fine.
Could be a software issue, or cable issue, or PC software issue.
