USB 3.0 support disabled, How do I enable USB 3.0 support ?

This version of the kernel 2.6.32-71.29.1.el6.x86_64 is supposed to have support for USB 3.0. But it does ot work. The controller is recognized at some level
lspci | grep -i nec
02:00.0 USB Controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 03)
but there is no support in the kernel for it

I need to obtain support for USB 3.0 since it will replace a very expensive Direct Attached Storage unit. Does anybody know how to do this? I don't need support for hibernation, if that is a roadblock.

USB 3.0 support is available, I have a mobo with USB 3.0 (and with SL6 installed on it) so I can confirm it, but I don't have any USB 3.0 device to test it.
Anyway see here:

And after loading the USB 3.0 kernel module (xhci_hcd):

You will notice that lsusb now shows an additional entry marked 3.0.

I made it work that way, but when my computer reboots it does not get loaded. How do I make that the driver does load before any other one in /etc/modprobe.d/aliases.conf or any other file? I have no idea how to alias it or make it load by default.

This should work:

The Redhat manual also suggests another way of doing it: link

If I turn USB 3.0 on my bios, my ports don't work at all....so right now it's disabled to USB 2.0. I'm going to try the above and see what I can do.

Great post...this needs to be addressed imo.

What USB 3.0 chip does your mobo use?

If it's the standard NEC one then your USB 3.0 ports should work in SL6.

It's NEC on my Dell M6500 Precision Laptop....if I turn it on in the BIOS, my ports become useless to "anything". What do you think? I have no USB 3 devices, so until now it hasn't mattered much to me. I'm packing my laptop now and moving venues 40 miles, I'll work on it when I get there.

I can't speak for your case obviously, but if I plug a USB 2.0 device in one of the USB 3.0 ports on my mobo after having done "modprobe xhci_hcd", I can access the USB 2.0 device (tested with a USB DVD burner).

Like I said I don't have USB 3.0 devices so I can't test those, but the USB 3.0 ports are definitely usable at least with USB 2.0 devices.

That works me for me too. I have the new kernel btw per the thread in Kernels section. I'm going to reboot and try again with USB 3.0 enabled in the BIOS. Thanks, tux, for that modprobe information. I've rebooted and my USB 3.0 ports still work normally...but I have the new kernel. I wish I would have tested before hand, maybe I'll boot on old one and test it.....

I'm glad it works for you now, too.

To make the kernel module load automatically at boot I created the following mini script according to the offical Redhat docs method linked to earlier:

/etc/sysconfig/modules/usb30.modules

It checks if the module has already been loaded (using the output of lsusb) and only loads it if it hasn't been loaded yet.

Yep, it's fine on reboot now without a modification....I just don't know if it's the new kernel or the modprobe command?

I will add to this thread that modprobe xhci_hcd was necessary on my Vostro 3350 13 inch laptop to get USB3 working.

Again, on reboot USB3 was active without modification. Newest SL Kernel as updated.

Hi,
as for your Q how to make your system to load module during startup, you can also remake your
/boot/initrd*.img file - this file is responsible for loading initial kernel modules during system bootup.

use 'mkinitrd --with=modulename /boot/initrd*img kernelname"

This is very common technique when you need to preload e.g. filesystem kernel modules, or some special raid modules etc...

cheers,
