If a USB2 device is used on a computer that is capable of only USB1.1 it will only run at USB1.1 speed. [They both need to be USB 2]However it should still worK OK. To see if your computer is capable of making use of USB2, go to device manager [start/control panel/system/click on the hardware tab, go down to USB and if it is USB2 it/they will have the word "Enhanced" next to it.[No "Enhanced", no USB2] As far as I am aware you would need USB 2 hardware to upgrade[eg, a card or hub] I don't think there is a downloadable/software solution but someone here may know better
.[BTW, it's possible to have both on the same computer so you have to be sure to use the correct port]
