Here are a couple of patches to support the DJM-450. Un-suprisingly, a device quirk is required just like the other DJM models. Testing was done by "xfz" from #xwax on Freenode. Perhaps this is useful for reference or if anyone requires information about this device. They were hesitant to have their full details in the commit log.
