USB 2.0 has a maximum interface transfer rate, or bandwidth, of 480 
Mbps (Megabits per second).  The performance depends on many 
factors including: CPU, file system overhead, number of attached USB 
devices and more.  Given these and other factors, in day-to-day use 
you can expect maximum, sustained transfer rates around 25 MB/s 
(Megabytes per second).  USB 2.0 is backwards compatible with USB 
1.1.  This means you can connect a USB 2.0 device to USB 1.1 port, 
and vice versa.  However, interface transfer rates are limited by the 
interface with the lower speed.  If you plug the Solo into a USB 1.1 
port on your computer, data transfer rates will be limited to USB 1.1 
speeds (up to 12 Mbps).
