无法安装USB

背景：MPLAB X IDE V4.05、XC32 V1.44 B、和声V2.05.01、PIC32 MZ2064 DAG169、PIC32 MZ2064 DAG169开发板具有显示功能。我一直跟踪到SysffsMediaAuthMealm中的SysSysfsMuntSt卷。这里是检查卷名和媒体类型。我的问题是，我找不到GysfsMetimaAdAgObj.fsMuntToT中填充了什么意思。我能找到它的唯一时间是在StultIG.I.C中，它设置为NULL，这对ME没有太大的影响。StythyIn.CysSyfsfIdiaAuxMaunel.CSOO，我不确定我的问题是什么，所以我将从这个开始。当一个const设置为NULL时，SysFSMoNTTABLE怎么能填充任何有意义的东西？如果这是不正确的，我如何让它填充一些含义充分？对不起，开放式的问题，谢谢您的帮助！

    Background: MPLAB X IDE v4.05, XC32 v1.44B, HARMony v2.05.01, PIC32MZ2064DAG169, PIC32MZ2064DAG169 development board with display.

I am trying to get a USB device to auto mount.  I have tracked it all the way down to _SYS_FS_MountVolume within sys_fs_media_manager.c.  Here is checks the volume name and media type.  My issue is that I can not find where gSYSFSMediaManagerObj.fsMountTable is populated with anything meaning full. The only time I can find it set is in system_init.c where it is set with NULL which does not make much since to me.

system_init.c

const SYS_FS_MEDIA_MOUNT_DATA sysfsMountTable[SYS_FS_VOLUME_NUMBER] =
{
    {NULL}
};


sys_fs_media_manager.c

SYS_FS_MEDIA_MANAGER_OBJ gSYSFSMediaManagerObj =
{
    gSYSFSMediaObject,
    gSYSFSVolumeObject,
    sysfsMountTable,
    NULL,
    gSYSFSMediaBuffer,
    0,
    0,
    false
};

static void _SYS_FS_MountVolume
(
    SYS_FS_MEDIA_TYPE mediaType,
    const uint8_t *volumeName
)
{
    uint8_t volumeIndex = 0;
    const SYS_FS_MEDIA_MOUNT_DATA *fsMount = (const SYS_FS_MEDIA_MOUNT_DATA *)&gSYSFSMediaManagerObj.fsMountTable[0];

    for (volumeIndex = 0; volumeIndex < SYS_FS_VOLUME_NUMBER; volumeIndex++)
    {
        if (mediaType != fsMount[volumeIndex].mediaType)
        {
            continue;
        }

        if (strcmp((const char *)volumeName, (const char *)(fsMount[volumeIndex].devName + 5)) != 0)
        {
            continue;
        }

        if (SYS_FS_RES_SUCCESS == SYS_FS_Mount(fsMount[volumeIndex].devName, fsMount[volumeIndex].mountName, fsMount[volumeIndex].fsType, 0, NULL))
        {
            if (gSYSFSEventHandler)
            {
                gSYSFSEventHandler(SYS_FS_EVENT_MOUNT, (void*)fsMount[volumeIndex].mountName, (uintptr_t)NULL);
            }
        }

        break;
    }
}


So I am not sure what my question is so I will start with this.  How can sysfsMountTable be populated with anything meaningful when it is a const set to NULL? Also If that is not correct how do I get it to populate with something meaning full?

Sorry for the open ended questions and Thank you for all your help!
