ehci_hcd and uhci_hcd work on LiveCD but no on installed system

Hello. In case you don't know, ehci_hcd and uhci_hcd are drivers for USB controllers (something like that).

With the LiveCD, all USB devices work perfectly. Using "grep .hci_hcd" on dmesg shows everything started fine.

After installing Arch Linux, the system seems to boot perfectly but all USB devices wouldn't work (including the keyboard).
Using the LiveCD to chroot into the broken install, /var/log/errors.log shows about 2 dozen errors coming from ehci_hcd and uhci_hcd.

Any reason why the USB controller drivers work perfectly on the LiveCD but fail miserably on the installed system?

Re: ehci_hcd and uhci_hcd work on LiveCD but no on installed system

For the sake of testing, could you try adding both modules to the MODULES array in /etc/rc.conf and see if that resolves the issue? Obviously if this works, it's just a workaround (not a structural fix). But at least you'll have a correctly functioning system to continue troubleshooting.

Re: ehci_hcd and uhci_hcd work on LiveCD but no on installed system

Adding the modules to /etc/rc.conf didn't work.

Here's the errors.log file (not all of it. just for one boot):

I have already tried:
1. adding "noapic" to the kernel parameters in grub2.
2. blacklisting ehci_hcd
3. removing ehci_hcd from mkinitcpio.conf

Re: ehci_hcd and uhci_hcd work on LiveCD but no on installed system

try removing your kernel paramaters, If you have set custom kernel paramaters.
What kernel are you using?

Foot note:
Now i found that you already have a thread on this. Why start new one?

Re: ehci_hcd and uhci_hcd work on LiveCD but no on installed system

I have the latest kernel (3.3.1-1).

Trying to boot with no parameters just gives more verbose output (because quiet is removed).

Re: Footnote:
So it would have a title that better describes the issue.
