I'm working on a STM32H750XB with USB. It works fine with the USB2_OTG_FS instance, but the speed is not reaching the maximum (only 875kB/s). I'm using the USB with diskio, FatFS and FreeRTOS.I'd like to enable DMA to make it faster, so I set hhcd.In...

The max speed for USB FS is 1.5MB/s in the most ideal case, according to the specification, so I wanted to be the closest as possible to this value.I'm doing "big" transactions, an f_read of ~65kB.
