lshw 中無人認領的設備
我在我的電腦中添加了一個帶有 2 個 USB3 埠和 2 個 sata3 埠的 PCI Express 控制卡。（http://www.ldlc.be/fiche/PB00121886.html）。
USB 埠工作正常，但插入 sata 埠的硬碟未出現在設備中。
我跑了 lshw，這裡是關於 pci 卡的結果：
*-pci:1 description: PCI bridge product: PEX 8604 4-lane, 4-Port PCI Express Gen 2 (5.0 GT/s) Switch vendor: PLX Technology, Inc. physical id: 5 bus info: pci@0000:05:05.0 version: ba width: 32 bits clock: 33MHz capabilities: pci pm msi pciexpress normal_decode bus_master cap_list configuration: driver=pcieport resources: irq:46 ioport:7000(size=8192) memory:d6100000-d61fffff *-ide UNCLAIMED description: IDE interface physical id: 0 bus info: pci@0000:07:00.0 version: 01 width: 32 bits clock: 33MHz capabilities: ide msi pm pciexpress cap_list configuration: latency=0 resources: ioport:7000(size=8) ioport:7400(size=4) ioport:7800(size=8) ioport:7c00(size=4) ioport:8000(size=16) memory:d6100000-d61001ff`似乎無人認領的 IDE 是罪魁禍首，它無人認領，因為系統找不到它的驅動程序。我怎樣才能找到使該 ide 部分工作所需的驅動程序？
到目前為止，我對 PEX 8604 的Google搜尋幾乎沒有返回任何關於 linux 驅動程序的資訊。

我找到了解決方案。該設備未被認領，因為核心無法正確辨識該設備。
使用核心 3.5，該設備列出如下：
*-ide UNCLAIMED description: IDE interface product: ASM1061 SATA IDE Controller vendor: ASMedia Technology Inc. physical id: 0 bus info: pci@0000:07:00.0 version: 01 width: 32 bits clock: 33MHz capabilities: ide msi pm pciexpress cap_list configuration: latency=0 resources: ioport:7000(size=8) ioport:7400(size=4) ioport:7800(size=8) ioport:7c00(size=4) ioport:8000(size=16) memory:d6100000-d6100但它仍然無人認領。
搜尋設備時
$$ 1b21:0611 $$我在核心郵件列表中找到了一篇談論它的文章。它告訴核心沒有將設備正確辨識為 ahci 設備，並向核心提出更新檔。
