I have this keyboard, but I have misplaced the little "usb stick" for bluetooth communication. Would any other usb stick do? Or do I need the same one?

Accepted Answer

That's right. Warning: the little "key" must be "Unifying" (with a little red symbol). Logitech has produced some that are not "Unifying". Logitech's software makes it easy to pair the keyboard and mouse to this "key". But it's not bluetooth. Perhaps Logitech can provide some, or Digitec can recover some.

Answer

Any of the Logitech ones. Just use the Unify software to connect the mouse and keyboard to the USB stick.
