Hi, 

I downloaded a USB device examples a I tried to use a Virtual Com Port Loopback.

This example works only if I manualy replug usb cable when the program is started. 

Anyone knows how can I do software reset?

I use a Coocox IDE and when I tried to run a debugger, I must connect stlink usb cable and usb user cable, then program starts, but the usb isn't configured. When i disconnect a usb user cable, stlink go to error. Because it's happend, I don't know what is the initialization sequence of usb after reset.

Best regards
