I am use stm32f207vc usb FS devices mode.
The IN_EP = 0x82 ;  OUT_EP = 0x03; the EP1 is no use.
and I want to know how to setting the FIFO_FS_SIZE??

the VCP demo is:
#ifdef USB_OTG_FS_CORE
 #define RX_FIFO_FS_SIZE                          128
 #define TX0_FIFO_FS_SIZE                          32
 #define TX1_FIFO_FS_SIZE                         128
 #define TX2_FIFO_FS_SIZE                          32
 #define TX3_FIFO_FS_SIZE                           0
 
and I change to
#ifdef USB_OTG_FS_CORE
 #define RX_FIFO_FS_SIZE                          128
 #define TX0_FIFO_FS_SIZE                          32
 #define TX1_FIFO_FS_SIZE                            0
 #define TX2_FIFO_FS_SIZE                          128
 #define TX3_FIFO_FS_SIZE                           0

the IN_EP2 can not be sent data???
