I have a PRS 48x48 Standard with the new style control box. My question is how good of Quality is the USB cable that comes with it and is it worth upgrading? Also how is it attached in the control box as I can't see the connection behind the input board?

I have been through Grounding the machine, Hubs, ect...

But I still get a comm error every now and then. Never while running a cut file but sometimes during going between a c2 command, K command, or from one file to the next...

Thank you for any help given...
