ux_device_class_hid_event_set stucks when transmitting using endpoint 2

Hello, I'm using usbx ux_device_class_hid_event_set(hid_inst, &hid_event); to transmit data from my stm32h7 board to host. My hid_inst has two endpoints, one for receiving data and one for sending data:

When I sends data using endpoint 0x82, this thread stucks at

x-cube-azrtos-h7/Middlewares/ST/usbx/common/usbx_stm32_device_controllers/ux_dcd_stm32_transfer_request.c

Line 112 in 57faa03

status = _ux_utility_semaphore_get(&transfer_request -> ux_slave_transfer_request_semaphore,

It seems no data is sent at all. I sniffed the usb, no data is received at host at endpoint 0x82.

Fixed. Setting more USBTX FIFO solves it.
