    Hello! I found in documentation function FS_SetFileWriteMode(FS_WRITEMODE_FAST). With this function write in file is faster then without this function (about 4 sec = 1Mb). But it also not fast. In documentation write that speed must be about 800kb/sec (32 - bit CPU running 72MHz). But I have only 256 kbyte/sec whith CPU lpc1768 100MHz. What can I do for send by USB in high speed? What settings I need set in embOS or USBH or emFS? Help, please. Thanks!
