It's a Logitech Setpoint issue...
I have a Logitech Easy Call desktop and have encountered the same thing. After trying generic drivers, different keyboard/mice, etc. I discovered the problem lies with an audio driver bundled with Setpoint 4.00BR. (Your mouse takes Setpoint 4.40, but I assume a similar problem exists.) Every so often the driver will glitch while a sound is playing, causing all other devices associated with Setpoint (in my case mouse and keyboard, to stop working. In my case I uninstalled Setpoint, manually removed all keyboard/mouse/sound drivers from Logitech through Device Manager, then reinstalled and the problem resolved itself. In your case, if you don't have a Logitech sound system, you should be able to resolve the problem simply by manually removing any Logitech sound drivers present and rebooting, then checking for driver updates for your sound card from the sound card manufacturer's website.
