If you should get functional problems or midi clock noise on your audio when arranging MIDI and USB sockets on the same panel, try this (it worked for me):
To avoid a ground loop problem between the MIDI socket (cable shield) GND and the GND of the (Neutrik-) USB socket via the common panel, remove the (default) connection between the USB GND and the outer metallic case within the Neutrik USB socket. Thus the USB GND is directly connected to the Axe's USB input without being additionally cross-connected to the panel/MIDI GND.
Good info, thanks! I ended up ditching the midi connections on the panel and kept the USB.
