ChibiOS Free Embedded RTOS

i want include usb functionality from "ARMCM4-STM32F407-DISCOVERY-MEMS" project to "chibios\testhal\STM32F4xx\ADC" project but i have

usbcfg.c:229:3: error: 'sduDataTransmitted' undeclared here (not in a function)

make: *** [build/obj/usbcfg.o] Error 1
make: *** Waiting for unfinished jobs....

I copied the files usbcfg.cand  .h in my project, I updated the makefile according to "ARMCM4-STM32F407-DISCOVERY-MEMS" project makefile and I enabled usb in halconf.h and mcuconf.h

i am going crazy...

In order to stop going crazy, enable HAL_USE_SERIAL_USB in halconf.h.

thank you very much Giovanni
