usbh_msc_get_last_error

Summary
#include <rl_usb.h>

U32 usbh_msc_get_last_error (
  U8  ctrl,
  U8  dev_idx
);
Description

The usbh_msc_get_last_error function returns the last error that happened on requested mass storage device. The argument ctrl is the index of USB Host Controller. The argument dev_idx is the index of device instance.

The usbh_msc_get_last_error function is part of the RL-USB-Host software stack.
