下图所示，使用USBX可以正常枚举，但是读U盘读写操作时就无法正常工作了，请问这种问题怎么解决？ image

Which platform are you on? Are you running some example with the platform vendor, with USBX integration?

使用的平台是 stm32f429bgt6+Threadx+Usbx+fileX，有的U盘使用是正常的，但是有的U盘就PID和VID可以识别，无法正常读写操作。调试发现，fx_media媒介的内容都是0，如下图所示，请问这种问题怎么解决或者怎么让该U盘正常读写。 LO)%_TP@4_NEYYO{1@AGTX

Do you have USB trace for the disks that can not recognize? It seems FX_MEDIA is not open, the possible issue can be MSC command fail, read data not correct or the file system not supported, trace can help to analyze the issue.

我也遇到了相同的问题。请问有新的进展吗？ @LiuChenghu

BTW, if you need EXFAT support, compile FX with FX_ENABLE_EXFAT and update USBX to latest version.
