我在计算机中添加了一个带有 2 个 USB3 端口和 2 个 SATA3 端口的 PCI Express 控制卡。 （http://www.ldlc.be/fiche/PB00121886.html）。
USB 端口工作正常，但插入SATA 端口的硬盘未出现在设备中。
我运行了 lshw，这里是有关 pci 卡的结果：
*-pci:1

看来 Unclaimed IDE 是罪魁祸首，它之所以未被认领，是因为系统找不到它的驱动程序。我如何找到使该 ide 部件正常工作所需的驱动程序？
到目前为止，我在 google 上搜索 PEX 8604 几乎没有返回任何有关 Linux 驱动程序的信息。

答案1
我已经找到了解决方案。该设备无人认领，因为内核无法正确识别该设备。
使用内核 3.5，设备列表如下：
*-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

但仍然无人认领。
在搜索设备 [1b21:0611] 时，我发现了一个邮政在内核邮件列表中谈论它。它表明内核未将该设备正确识别为 ahci 设备，并建议对内核进行修补。

我将补丁应用于内核3.5的源代码并重新编译，现在它可以工作了。有关信息，该补丁包含在 3.6 及更高版本的内核中。
