CONFIG_USB_MON=y is fine for me on my server running 3.14.something: I get a few lines of messages on a tty when I attach a drive, but no continuing output. Of course, I do not boot with a usb device both attached and powered on (in the past, that was asking for trouble). I assume you have turned on too much debugging information somewhere. I'll attach my config.gz - it will obviously not match your hardware, but if you diff it to your .config you might see some areas to investigate. ĸen -- Nanny Ogg usually went to bed early.
