USb Stick drive Monitor Software

Now that the usb drive has become prevalent and the seniors are starting to use them it is hard to know which port they are using and if it is a 2.0 or 1.1 one ,so i would like to find a free monitor to do this ,I work with seniors helping them get up and running on the net they are many that they have to scrimp to just get a computer but it keeps them in touch with children and Grand Kids especially thanks in advance bye for now.rgourlay
