Disable the usb_midi driver (move /boot/system/add-ons/kernel/drivers/dev/midi/usb_midi out of that folder [bypassing any warning it may give you about messing with the system!]), then reboot (just to make sure) and plug your KX8 in again. If it doesn't lock up this time (as I hope!) the K/B should still show up in the /dev/usb tree, and you can run listusb -v on it. If you can do that, please post the output. Might give us some clue as to what's happening. Thanks, -- Pete --
