Hello there. I tried to use the search for this problem, but nothing came up.

My problem is as follows, USB 3.0 ports work, none of my USB 2.0 work. I've tried building my kernel manually, and with genkernel, but I'm not sure if it is a kernel problem, since my usb ports work fine in the environment I installed Gentoo from (Arch LiveUSB, and Ubuntu). Some people said, that enabling IOMMU in BIOS could fix it, but it didn't for me. I've tried every single kernel I could find, but the usb ports act the same. My USB ports work normally on Arch Linux.

My hardware is as follows:
AMD FX-8120
Gigabyte 990XA-UD3
8GB 1333MHz DDR3 RAM
Geforce GTX 650
250GB Sata HDD

My dmesg is full of errors like this:

Code:

[   76.668814] usb 4-3: device descriptor read/64, error -32

I tried asking about this on IRC, but I did not get an answer. Maybe someone here knows what could be the cause? :) Thanks in advance.

what kernel version does arch use, and which one do you use with gentoo?

3.9.9 at least on the LiveUSB, but as I've said, I have the same problems on every kernel I've tried so far. I currently use 3.10.0 on Gentoo.

Disable C1E in the BIOS if you have it enabled, and also as a test try to disable PowerNow as well.
It's a bit strange that the Arch Kernel should work but yours doesn't. Can you perhaps try to boot
the arch kernel with your gentoo installation?

Did you ehci compile into your Kernel?

Yes, I did. As I've said I've tried both self configured kernels (not a new Gentoo user, been using since 2006 or so) from kernel seeds, default config, and genkernel. :)
Anyway, with Arch's kernel, USB works properly.. I wonder what is so different in it.

Here are the kernel .config files for Arch 3.9.9 kernel and Gentoo 3.8.13 kernel made with genkernel if someone could take a look, please? :)

You should try 3.9.9+ on Gentoo - it could be that there was a USB bug fixed in the 3.9 series..
USB3 ports are still very new and may do some bad stuff especially with integration.

Well, USB3 ports are the only working ports here. And I've tried random kernels from 3.8 to 3.10.0 and none of them work. :( Gonna try compiling a kernel with Arch's config to pinpoint if there is something wrong in the stock config.



Edit: With Arch's config everything seem to be working properly. Now, I gotta find out what options I need to check in kernel config... as I prefer a minimal kernel. :roll:

It's strange that the usb ports do not work with stock genkernel config, though.

Here is my current non-working kernel config
I'm having a hard time to find an option to enable..

enable these 2 options in your kernel please:
+# CONFIG_USB_EHCI_ROOT_HUB_TT is not set
+# CONFIG_USB_EHCI_TT_NEWSCHED is not set

Enabled, still not working. :( This problem is starting to get kinda weird.. Here is my dmesg

Edit
: Okay! Got my USB ports working by enabling CONFIG_AMD_IOMMU, however now the Nvidia binary drivers stopped working. I wonder if IOMMU blocks using my GPU and if there is any workaround for using the binary blob nvidia drivers. Here is the Dmesg.

I guess using IOMMU is just an "workaround" for working USB ports..I plan on running VMs as well, which is the primary reason why I bought this board...


Edit 2

FINALLY! I added vmalloc=256M iommu=pt to Grub2 command line and everything works nicely! :)

That was so odd that you ought explain yourself. How come those settings helped you with your USB ports? How did you come by that solution?

I suspect the iommu=pt option did it. BIOS has buggy iommu tables, best to disable it altogether.

None of my USB ports work if IOMMU is off in BIOS. No idea why. My Ethernet port doesn't work either when it's off.

I came by this solution when I realized that PCI devices are managed a bit different when using an IOMMU. And it seems to work as an workaround. There seem to be many users with the same chipset (and problems). :) Usually a BIOS upgrade fixes it, but Gigabyte hasn't supplied one for my board.
