我有一台安装了 Debian 9 和内核版本 4.20.0 的 DELL Latitude 5590 笔记本电脑。不幸的是,板载 sd 读卡器不起作用。读者遵循模型:
瑞昱半导体有限公司RTS525A PCI Express读卡器读卡器
的输出lspci -v
01:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader (rev 01)
Subsystem: Dell RTS525A PCI Express Card Reader
Flags: bus master, fast devsel, latency 0, IRQ 127
Memory at ef100000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [80] Power Management version 3
Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [b0] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [148] Device Serial Number 00-00-00-01-00-4c-e0-00
Capabilities: [158] Latency Tolerance Reporting
Capabilities: [160] L1 PM Substates
Kernel driver in use: rtsx_pci
Kernel modules: rtsx_pci
根据https://cateee.net/lkddb/web-lkddb/MISC_RTSX_PCI.html所需的驱动程序是rtsx_pci
.
如果我现在用 modprobe 检查什么都不会发生:
root@sandbox:/dev# modprobe rtsx_pci
root@sandbox:/dev#
root@sandbox:/# ls /lib/modules/4.20.0/kernel/drivers/misc/cardreader/
rtsx_pci.ko rtsx_usb.ko
root@sandbox:/#
dmesg
这是输出:https : //pastebin.com/raw/HQAX45b4
不幸的是,我的知识到此结束;我怎样才能让它工作?
