Hi there,

I am working on STM32FDiscovery and USB CDC. For this purpose I used:
https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Discovery/DispForm.aspx?ID=1311
(I do use CooCox). Well Compiling + Linking successes. The USB Device is recognized (Windows sound) but marked as "USB device not recognized". However PID is 0x0000 and VID 0x0002.

Any Ideas? Has anyone had this problem?

Thanks a lot
