Hi,

My application includes USB with mass storage class, I am using STM32F103VE MCU running at 72Mhz. Sandisk uSD(8GB, Class 10) used with SDIO  interface.

I have used USB MSC code from STM32F1 library
(STM32_USB-FS-Device_Lib_V4.0.0\Projects\Mass_Storage\MDK-ARM).

I have made my own device to test this software and it is working fine because I have tested USB HID and USB MSC.

My only problem is that I am getting ~50KB/S speed in USB MSC, how to increase it?
It would be really helpful if any one can give suggestion or workaround for it.
