Sample Usage

This code is made for FWs 0.990-1.69 as it used the SceUsbstorVStorForDriver library which was removed in some recent FWs. 

int start_usb_storage(void) {
    int ret = SceMtpIfForDriver_0xFDF8C3C0(1); // stop MTP driver (it calls sceUsbMtpStopForDriver)
    printf("Stop: 0x%08X\n", ret);
    ret = sceUsbstorVStorSetDeviceInfoForDriver("\"PS Vita\" MC", "1.00");
    printf("SetName: 0x%08X\n", ret);
    ret = sceUsbstorVStorSetImgFilePathForDriver("ux0:/umass/fat.img");
    printf("SetPath: 0x%08X\n", ret);
    ret = SceUsbstorVStorStartForDriver(USBSTOR_DEVICE_TYPE_DIRECT_ACCESS_BLOCK_DEVICE);
    printf("Activate: 0x%08X\n", ret);
    return 0;
}

int start_usb_storage_unchecked(void) {
    int ret = SceMtpIfForDriver_0xFDF8C3C0(1); // stop MTP driver
    printf("Stop: 0x%08X\n", ret);
    ret = sceUsbstorVStorSetDeviceInfoForDriver("\"PS Vita\" MC", "1.00");
    printf("SetName: 0x%08X\n", ret);
    ret = sceUsbstorVStorSetImgFilePathForDriver("ux0:/any/path/here.img");
    printf("SetPath: 0x%08X\n", ret);
    // Activate without test
    //*(int*)0x013F9054 = 0; // set 1 for RO access
    ret = sceUdcdStartForDriver("USBDeviceControllerDriver", 0, 0);
    printf("StartUSB: 0x%08X\n", ret);
    ret = sceUdcdStartForDriver("USBStor_Driver", 0, 0);
    printf("StartStor: 0x%08X\n", ret);
    ret = sceUdcdActivateForDriver(1491);
    printf("Activate: 0x%08X\n", ret);
    return 0;
}

int stop_usb_storage(void) {
    int ret = sceUsbstorVStorStopForDriver(1); // stop storage driver
    printf("Stop: 0x%08X\n", ret);
    return ret;
