Solaar mostly changes configuration and helps pairing devices, but it's not part of the drovers, so it might not help you. Anyway I dump some info about dongles here just in case, if you find your devices are compatible you might use Solaar to reset the pairings.

IIRC, there are three types of dongles: the old basic ones, that only work with one particular device, the not-that-old "unifying" dongles (they have a red logo with a star or ray of light), and the new ones that are called "bolt" (green logo with a bolt in it).

I have mostly experience with the "unifying" receivers. Those can pair to any "unifying" compatible device, and keep connections with up to 6 devices. Bolt dongles work similarly but with better encryption.
