Is that a bios option, or just behavior you found?

Same Q.

Same Q.

I'm thinking that as a means of making a notebook better able to plug in
to docking stations and generally other devices for temporary "full
size" support, the bios may be doing this for "convenience". That and
managing hot plugging of devices on a laptop probably is "enhanced" for
this particular scenario. I would not expect a desktop machine to do
this, although a desktop would have options in the bios whether to
activate USB or ps2 ports. The bios "convenience" features of a laptop
could conceivably get in the way of allowing the o/s to do the work.

Can't answer that, not enough usb knowledge. But...the general scheme is
that most "mouse" device listings in /dev/ are just sym links to the
underlying device, whether it is a ttyS# (serial port), psaux (ps2
mouse), or something else.
