1. The receiver is not compatible with normal Logitech Unify receivers. Keyboard on a receiver, mouse on the other. Adjustment SW for keyboard and extra adjustment SW for the mouse. There are blocked on the PC two USB ports.
2. In normal mode, the double can not be programmed on the middle button !!! You can assign the button while a lot, but the double is missing from the list. Why Logitech does not offer this feature to me is a complete mystery, especially since it is explicitly mentioned in the instructions.
Quote: "Choose the desired mouse function from the options displayed: left click, right click, middle click, Previous, Next,
Double, increase resolution, reducing resolution, change resolution, standard resolution,
Resolution switching, mode change (G300 / G600), G-circuit (G600) and (for some devices) Top
scroll, scroll down Scroll left and Scroll right. "
For all who love the double, like me, here is the guide on how to teach it anyway mouse:
If one uses the internal memory of the mouse, it does not work! The double can not be assigned.
My solution:
1. The mouse of internal memory turn on automatic gamertag.
2. It will be recognized a few games and there is a default profile. -> Edit Current Profile
3. Then the middle mouse button to assign the double (assign a new command -> Mouse function -> double-click).
4. Use this profile as the default (default is already so)
Then it goes on until you start a game from the list.
