Why can't Solaar load information about my m510 Logitech wireless mouse?

Created by: rohantib

I have the mk550 Wireless Wave combo. Solaar picks up my keyboard just fine, showing it has an encrypted connection and full battery. However, my m510 mouse is shown by Solaar to have an unknown amount of battery charge and an unencrypted connection. The options to enable smooth scrolling and side scrolling are also greyed out with a warning icon next to them saying that read/write operation failed, but the mouse still works fine. So why is this? What can I do so that I will see accurate information? And if it isn't an encrypted connection, how do I make it secure?
