Mouse scrolling in Chromebook.

[Mzee]

what exactly is the problem?

Sometimes the mouse only scrolls down, sometimes its notchy, sometimes smooth. I varies on different websites. The wired mouse does the same. Another thing is, there are 2 A type USB ports, and the mouse will only work in one of them. USB sticks are mounted Ok in both ports. There are also 2 C type USB ports. I also have an HP Chromebook, & it does the same.
