| 24 | ---help--- |
| 25 | The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0 |
| 26 | "high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware. |
| 27 | If your USB host controller supports USB 2.0, you will likely want to |
| 28 | configure this Host Controller Driver. |
| 29 | |
| 30 | EHCI controllers are packaged with "companion" host controllers (OHCI |
| 31 | or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports |
| 32 | will connect to EHCI if the device is high speed, otherwise they |
| 33 | connect to a companion controller. If you configure EHCI, you should |
| 34 | probably configure the OHCI (for NEC and some other vendors) USB Host |
| 35 | Controller Driver or UHCI (for Via motherboards) Host Controller |
| 36 | Driver too. |
