Code 25 locks up when connected via USB


I'm currently experiencing a problem where the amp locks up on a regular basis.  When it happens, none of knob (gain/low/mid/high/volume) and button (pre FX/amp/mod/del/etc) settings take any effect: e.g I can set a mod effect, but the sound doesn't change.

The amp is paired with my iPad, but when this happens, the iPad is not connected and not even in range.  It seems to be related to having the amp connected to my iMac via USB: after frequent cases of this happening, I unplugged the USB cable and the problem instantly went away.
