Hi, I'm trying to run the ''USB Device VCP example'' using the gcc (sourcery-lite) tools.  I can build it and it appears to be running (led is blinking and the message ''USB device library started'' comes out the UART; but then I get ''Unknown Device'' on the USB side when I plug it into a PC.  

Has anyone built any of the USB device demos with GCC? #usb

Ok, great. That cleaned up the map, thanks much.  Shoulda realized that myself.

Anyway, still (not expecting an answer here) I'd like to know why the linker did that in the first place.Thanks again, Ed

By the way, for anyone else reading this, I made the changes for this to

optionally work with USART6, which is the default configuration for the DB9 connector that comes with the STF4BB board.

This is a quick port of the MicroSD + FatFs to the STM32F4DIS-BB platform
