Hi all,

I am facing a strange problem. I have made a usb application on STM32F103RBT6 and it all works good....but if I remove the debugger (J-Link) from the board, the application does not work. I mean nothing works. My board is connected to USB and I am sure there is no power issues.

There might be some settings in the startup.s file or something else that I am not aware of. 

What can be wrong?
