i want to build Audio_playback_and_record project for usb library but there are some problems. i downloaded this project (stsw-stm32068.zip) from here.
i have changed defined symbols as below. wrote MEDIA_USB_KEY instead of MEDIA_IntFLASH which was default.

but compiler gives following errors for this setting:
