AOC E2251FWU USB monitor flashing

I'd try an externally powered hub, or you could try using the USB Y cable connecting the "power only" end to a different power source (not on the same laptop).
Given that the other devices work OK I'd think about a degradation of the electronics more than a SW issue.

Cheers,
Carlo

Thanks Carlo. I'll try the powered USB hub. The monitor has a single USB input, so there isn't a "power only" option for that.

I also found an OS X USB Debug Kit here that I'll try: https://developer.apple.com/hardwaredrivers/

The external powered USB hub worked flawlessly with the AOC monitor. The debug logs contain no reference to DisplayLink. So I think that the driver is not the problem.
