I bought a JB Burrows wireless mouse a few months ago, and the light defocussed after a while (I think, buttons were fine but tracking only worked on glossy surfaces). I replaced it with a Logitech M705 which should be much better...but I either lost the base station or it never had one to begin with (can't clearly remember whether I saw it in the packet, have looked mostly everywhere at home).
I do still have the JB Burrows base station, though. Could I flash it with Logitech firmware? If I can, how would I do that? Neither station uses a generic wireless connection, so using the Burrows station without changing the firmware wouldn't work.
