12/8    Just exactly how fast is USB1.1 vs USB2?
        \_ Isn't this highly googlable?
           \_ You think we'll all think you're cool cuz you made up
              that adj.  But we don't.
              \_ You imply too much. "Googlable" has been around for awhile.
        \_ USB 1.1 has a data rate of 12 Mbps. USB 2.0 has a data rate
           between 120 and 240 Mbps. To a rough approx. 2.0 is between
           10x and 20x "faster" than 1.1. You should really have google'ed
           this.
        \_ Thought 2.0 was 480 mbps...anyway USB is CPU dependent,
           thus my experience is that when I'm pushing lotsa data
           through the bus my computer starts chugging.
        \_ Someone erased this, but it's 12 Mbs versus 480 Mbs. --dim
           \_ The speed is also dependent on the devices. The slowest
              device dictates the speed of all the devices. If you
              plug in a 1.1 device on a 2.0 chain, the entire chain
              degrades to 12Mbps.
