Logitech Master MX not working

[aoaaron]

Hi, my master MX connects fine. I have installed the \Logitech Options' application and it works fine for a while. however after 5-30 minutes, the driver or app stops working and yosemite/apples default settings take over and all the extra buttons become useless.

can someone PLEASE HELP me fix this

So are you using the latest Logitech driver? Is it listed as Yosemite compatible?
Posted the issue to Logitech?
If you look in Activity Monitor is the driver listed as running or unresponsive?
Any app/driver crash error logs or messages?
