I have a newer revision of Qnap's TS-119 P II single-bay nas. It runs an armv5te Feroceon cpu. The older revision runs on linux 3.6-rc7 just fine. The newer revision has usb3 ports at the back instead of usb2, and these are not detected. lspci and lsusb detect nothing. /sys/bus/pci/devices is empty.
Qnap provides sources for their kernel - 2.6.33.2 with lots of patches. The usb3 ports are detected by an etxhci driver. The author of this file, Sarah Sharp, points at pci initialization code as the likely culprit. The fact that Qnap's 2.6.33.2 kernel has 8800 Kb of drivers under arch/arm/plat-feroceon that don't exist in vanilla linux agrees with this. Now I'm at a loss as to how to proceed. Transplanting this entire tree under the new kernel and getting it to compile might be possible, but vanilla linux cares about more hardware than just Qnap, and I have not enough knowledge to determine if different Feroceon platforms are different enough to need different drivers. I could also start upgrading the Qnap tree with 2.6.34, 2.6.35 etc. taking small steps. It might also be that judicious tweaking of some PCI things (signatures? locations?) might be enough to support these USB3 ports. Some more information is posted at http://forum.qnap.com/viewtopic.php?f=147&t=61716&p=290123 including dmesg output etc. I would really like someone experienced in either arm or pci or both to point me at what to do next.
