Hello,
Sorry for coming back to this after one month, but my laptop decided
to die and only yesterday I received it back.
So, when I disable usb-audio, mass storage shows the same behavior
(multiple resets), and when I disable mass storage, usb-audio doesn't
even load:
{{{
[ 6893.787825] usbcore: deregistering interface driver usb-storage
* i plug the KAOSS pad in *
[ 6914.954294] usb 2-1.1.1: new full speed USB device using ehci_hcd
and address 13
}}}
And that's it.
Shouldn't usb-audio work independently of mass storage?
Thanks once again.
Cheers,
Pedro
