Hi,

Development board: STM32u5a9j-dk Code: en.stm32cubeu5-v1-4-0\STM32Cube_FW_U5_V1.4.0\Projects\STM32U5x9J-DK\Applications\USBX\Ux_Host_HUB_HID_MSC\STM32CubeIDE

issue: Two Kingston U disk, U disk format is FAT32, connected to the computer can read and write normally, connected to the MCU can be normally enumerate and identify, when "App_File_Create", one of them can normally create files and read and write, but the other one fails to create. Trace found that in the _fx_file_create function if (media_ptr -> fx_media_id ! = FX_MEDIA_ID) returns the error code return(FX_MEDIA_NOT_OPEN); , add print media_ptr -> fx_media_id has a value of 0 .

Can you help to analyze what is the reason?
