My Epson WF-7525 works perfectly with Ubuntu 15.04, but I have a very specific annoyance: whenever I resume my machine or plug in a USB device, the scanner comes alive as if it's briefly scanning, then stops.
It's rather noisy, and plugging in a phone nearly always triggers it. The printer-scanner seems to come out of its low power state, and I've found that I can only stop it by turning the WF-7525 off completely. This also happens for other Ubuntu machines that have the printer installed, but not for Windows or Mac machines.
I get the impression that Ubuntu is polling devices, and this is how the Workforce happens to respond to it, but I couldn't figure out which process is responsible or how to prevent it from doing so.
Is there any way to troubleshoot what's causing this, or how to disable it?
