I don't want to hijack a bug report (see my test at #22), but I strongly believe that this should not be offloaded to "a buggy BIOS".
I am experiencing the same behaviour on quite a different system, it is (obviously?) a regression since it worked (on the same system) under 15.10 and previous versions. I agree that my BIOS is rather old but the notion "well, bad luck, you will have to buy a new motherboard to be able to use your mouse like before" gives me the creeps. I hope I am overreacting :-) For completeness, my BIOS-Version BIOS Information Vendor: American Megatrends Inc.
