ZOOM r16 major problem

Hey guys, i have using my r16 for 4 years now, bought in new. But suddendly this problem has showed up: when i plug it to my computer, the computer won’t recognize it. The “audio interface” box on te zoom r16 just stays blinking, like it never connects successfully. I’ve tried on different computers, with different cables, reinstalled the latest drivers, and still nothing happens. It just never ceases to connect properly. Any suggestion? I use a 2011 MacBook Pro 15" with El Capitan

Have you managed to solve your problem? I’m having the same issue now.
