Hi,friends。when I running the usb examples --usb_device_msc_sdcard_lite.In the  "usb_device_config.h" , there  are some configuration definitions of  USB  device config are not very clear.
1. what does the " LPCIP3511  "mean?
#define USB_DEVICE_CONFIG_LPCIP3511HS (0U) the usb_device_msc_sdcard_lite  demo  ,about the  sd clk config is 
CLOCK_SetClkDiv(kCLOCK_DivSdioClk, 2U, true);
but in the sd_fatfs demo  about the sd clk config  is
CLOCK_SetClkDiv(kCLOCK_DivSdioClk, 1U, true);
I think this is all about SD card reading and writing, why is the clock configuration different?
