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

And here, the device is disconnected from USB, but I doubt that is related to the driver stack. The only thing I can currently think of is that the device draws too much power at this point, and a voltage brown-out causes the device to reset. Can you try a powered hub, or is this device powered by an external supply anyway?
It's got its own power supply :)
Did you successfully use it on the _same_ hardware under Windows?
Haven't tried... I don't have windows on this machine :/
Could you try to temporarily disable the snd-usb-audio driver (move the module away or build a kernel without support for it) and then see whether the mass storage function works stable? And then the other way around - disable USB mass storage and try the audio function only.
Maybe that can give some hint.
