(hi all) ...after I transplanted my old Asus M3N78/AMD 955 from Antec Solo case into Lian-Li case. Was at it all day, ... I thought I might have got the centre two + and - pins the wrong way round on the board but, no they were fine and anyway, every time I plugged the nano-receiver into a different one of about 11 or more USB ports, driver got installed. After over an hour of rummaging, the penny finally dropped, I've got two M305's and the wrong nano receiver was in the Antec case i.e. I hadn't swapped them ! Sooooo easy to get caught out over something simple !
