Thanks for posting. I’d be happy to answer your question!
In our limited testing of the USB3-HUBME with ChromeOS we have found it to be compatible. As Google controls ChromeOS that support can change at any time, but as of right now both the Ethernet and USB hub work. I would recommend purchasing one adapter to test with (as we do not have your exact Chromebook to test with in house) to ensure it works well in your environment. If the adapter does not work properly we have a no-hassle 30-day return policy via the automated system at amazon.com/returns.
Let us know if you have any additional questions.
