Problem with USB Debugging

Hello,

I'm developing with STM32373C-Eval-Board using the ST USB-FS-Device-Lib und µV4. Now I want to communicate with my board via USB. In normal mode, (almost) everything works fine, but when I'm in Debug-Mode, my OS (Windows 7 32-bit) says the USB-Device is not known.
Does anybody know why and how I can debug USB?

Thanks in advance!

Note that USB is time critical, so in debug mode you may fail some hard timing requirement making Windows fail to correctly enumerate your device.

You'll want to use techniques which don't stop the processor, instrument your code, outputting diagnostic data via the serial port, understand what your code is doing, and what the hardware is reporting.
