Hi, I'm trying to implement stm32f7 discovery cube package example. (USB Mass Storage) in High speed mode. I inserted microSD card into slot. after i build and load the image into the memory , i can see the files inside microsd card.

but when i start to copy and paste these files to another location . i can not get the true speed. (while writing reading) I mean I choose HS mode (60Mb/s) but transfer speed is too low. I made everything in the readme.txt file. but i can not implement this fw. example (high speed mode). Can anyone to help me??
