Bug#545314: be sure to also have PS/2 keyboard plugged into adapter
OK, I think I am beginning to get the picture. At the time one plugs it
into the USB socket, for this particular device, one should be sure to
have a keyboard also plugged into it, if one wants to use the mouse.
(But at least in my later tests, if didn't disable the laptop's own
I.e., both PS/2 sockets need to have something plugged into them.
I'm not sure if it is the devices' fault, or Linux's. I'm willing to do
any tests as instructed though.
