To me, it sounds like either a bad cable or a faulty board on the printer. I've seen this message before when my Dad's Garmin (satnav) decided to brick itself, as it would display this message when plugged into a USB port without looking for a driver. It's different from the USB driver failure message where it first brings up a 'Found new hardware' message.
I have seen a similar issue a neighbour's multifunctional printer (I think also an Epson.) The owner said it worked fine up until after a night with a nearby thunderstorm. That printer continued to work fine as a standalone photocopier, but its USB board likely got hit by a surge from the thunderstorm.
First I would suggest checking if the unit itself is working, i.e. try photocopying something. If it can't do that, then the printer itself is likely dead. If it copies fine, then I suggest trying a different USB cable. Try different USB ports also, such as a USB3 port or with a hub. For example, my USB Wi-Fi adapter will only work on my PC's USB3 port (on a USB3 PCIe card) even though it's a USB2 device, however, the USB2 ports work fine with other devices.
