I've seen that before with logitech mouses. Usually people just get a new mouse and it solves the issue

but to be sure:
first check if middle mouse button works in other applications(check in browsers.)
or
Try to insert the cable into a different port. Avoid those front ports.
or
If you have multiple monitor setup, disable one screen ant try again.
or
if you have that, try working in older maya, maybe 2014. Maya is well known for its issues with drivers. I have simmilar issues with genius products (they are great but maya just stops responding to them at some point, always have a spare one)
