Please post a bugreport upstream @ http://bugzilla.kernel.org/. Make sure your device is not broken, test it under another OS to confirm it works properly.

After seeing the same messages as you for a internal device which is not connected i found out that this error messages be not helpfull in every situation and the important point is more "do your device works or not".

Here the infos what i found:

The device is not broken. In Ubuntu dmesg shows nothing when plugged in.

Than perhaps the Ubuntu kernel is patched because the little what i understand is that instead of elder kernel versions this message can comes earlier as before and is not even bad. Not nice but on the other hand an information is better than no information. -)

you could try to load your usb hostcontrollers in this order in rc.conf or mkinitcpio.conf:
MODULES=(ehci-hcd uhci-hcd)

Thanks, I'll try that.

status on this?
Comment by Attila (attila) - Saturday, 29 November 2008, 07:22 GMT
In my case this messages gone away since i use kernel 2.6.27.7 (own kernel package) and so perhpas jonas could recognize the same if kernel26 steps to the same version.

I confirm that loading ehci-hcd before uhci-hcd solves the problem. I have a midi to usb cable and on Ubuntu (kernel 2,6,24) it worked but not on Arch (kernel 2,6,27). In another Arch box with an old kernel (can't check right now) the cable worked fine without any special configuration. Great to know that there is a workaround.
