Unclaimed device in lshw
16,659
I have found the solution. The device was unclaimed because it was not known correctly by the kernel.
Using a kernel 3.5, the device was listed as below:
*-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
but it was still unclaimed.
When searching for the device [1b21:0611] I found a post in the kernel mailing list talking about it. It tells that the kernel does not identify the device correctly as an ahci device and propose a patch to the kernel.

I applied the patch to the source of kernel 3.5 and recompiled and it is now working. For information, the patch is included in the kernel in the release 3.6 and above.

I have added in my computer a PCI Express controler card with 2 USB3 ports and 2 sata3 ports. (http://www.ldlc.be/fiche/PB00121886.html).
The USB ports are working correctly but the HDD plugged in the sata port is not appearing in the devices.
I ran lshw and here the result concerning the pci card:
*-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`It seems that the Unclaimed IDE is the culprit and that it is unclaimed because the system found no driver for it. How can I find which driver I would need to make that ide part working?
So far my google search for PEX 8604 return almost nothing concerning a linux driver.

Admin over 11 yearsI think PEX 8604 is just the PCIe bridge. It doesn't really do anything but taking care of interconnections.
lspci -v -s 5:5should show a lot more information. -
Admin over 11 yearsFor lspci,
07:00.0 IDE interface [0101]: Device [1b21:0611] (rev 01)is the device. And in lshw, it does showcapabilities: ide msi pm pciexpress cap_list. Is the drive plug in to that interface working? spinning? Has power? -
Admin over 11 yearsThe disk was properly plugged. I solved my problem. Check my answer.

Drakes over 3 yearsIf anyone comes to this years later, if you compile Linux from source, make sure to include the usb kernel modules as well.
