question about the outputs. on my older box it only has USB1.1 and USB2.0 ports, no 3.0 on this rig. unSpawn, why would yours not show the difference between the 1 and 2? should i have placed a space between 3]\.[ so 3]\ .[
sorry im a bit slow on this, but if i enterprit your egrep correctly it is looking for USB.<any number between 1 and 3 to include both those numbers> then a .0 or .1 so it should be looking for USB.1.1 or USB.2.0 or USB.3.0 am i correct?
