As far as I can see, none of these changes make much of a difference.
(The TT scheduler should affect only low or full speed transfers.)

Please change line 376 to

printk(KERN_DEBUG "completed URB %d, status: %d, bytes: %u\n", err, urb->status, urb->iso_frame_desc[0].actual_length);

and show the logs for both maxcpus=1 and multiple cores.

Can you try this on any other computer?

Is this really an unpatched kernel.org kernel?
What USB controller do you have (see lspci)?

I'm not sure if this is a problem with the EHCI driver or your USB
controller, but both would be appropriate for the linux-usb list.
