Can I use a computer mouse with a Chromebook?
Almost any USB mouse will work, at least for left & right buttons and scroll wheel:
Yes, any USB plug and play mouse should work with a Chromebook. I have to say I rarely use one with mine though, as the trackpad is phenomenal.
Yes, as Hovsep says, the mouse will work fine as long as it is standard. Special features such as extra buttons or programmable buttons will probably not work, but the basic features will.
Many accessories like Mac or Windows USB drives, computer mice, and keyboards work well with the Chromebook.
