i am using 2 unifying devices a mouse (M705) and keyboard (K520). Why does Logi Options+ only give me options for mouse and never show anything about the keyboard I can not even reinstall it i can not delete it it can not be found. but if i install unifying software it is there but after running it once it updates to logi options+ and then back to square 1 no keyboard. what is the problem with showing a keyboard and any options like the mouse. is there a fear that the keyboard is going to create a nightmare for logitech?
