将 SD 卡插入笔记本电脑的内置读卡器时，我的系统无法识别它。我已经尝试了 2 个带有适配器的 micro-SD 卡和 1 个 SD 卡，它们在 Windows 上都工作得很好，这意味着我可以排除读卡器或 SD 卡的问题。 SD 卡可以由外部 SD 卡读卡器通过 USB 进行访问，因此 SD 在 Linux 上并非无法访问。
我有一台 HP Pavilion 游戏笔记本电脑-dk1xxx，运行 Fedora Linux 39 工作站，内核版本为 6.7.9-200.fc39x86_64。我的笔记本电脑确实可以识别我的读卡器：

运行时lsusb，无法识别，并且在lsblk或中sudo fdisk -l，找不到SD卡：

插入后，也没有文件，/media并且/dev没有任何 mmcblk 设备。
在检查时dmesg，我看到一个错误：首先初始化 SD 卡时失败，然后大约每 10 秒，它会说“超时等待硬件中断”，这与这个探针:

向后滚动时，我也看到了这一点（我真的不知道它是否与此有关，但可能是这样）：

有人可以帮助我吗？这是驱动程序的源代码（包含在内核中）（如果有人能够用它做某事）。
