5 27-Dec-2002
7 The EHCI driver is used to talk to high speed USB 2.0 devices using
8 USB 2.0-capable host controller hardware. The USB 2.0 standard is
9 compatible with the USB 1.1 standard. It defines three transfer speeds:
11 - "High Speed" 480 Mbit/sec (60 MByte/sec)
12 - "Full Speed" 12 Mbit/sec (1.5 MByte/sec)
13 - "Low Speed" 1.5 Mbit/sec
15 USB 1.1 only addressed full speed and low speed. High speed devices
16 can be used on USB 1.1 systems, but they slow down to USB 1.1 speeds.
