In the last 24 hours I have been getting lost connection Errors, as seen below?

Does anyone have any insight as to how to fix this issue?

I have Indigo version 4.1.1
and Interface 2414U

These are USB level communication problems between your Mac and the PowerLinc. It could be: bad USB cable, bad USB cable connection, bad PowerLinc, or some other USB device causing a conflict (Were you operating any other USB device when it failed? Syncing an iPhone?).

Try swapping out the USB cable. If that doesn't help, then try other USB ports. Do you have it plugged into a USB port on your Mac (versus in a hub)?
