3.5.7 USB Connector

The IXP420 processor's USB is integrated, USB 1.1-compliant and supports all standard

device requests issued by any USB host controller. It is an USB device-only controller.

The interface supports full-speed operation and 16 endpoints and includes an integrated

transceiver. There are six isochronous endpoints (three input and three output), one

control endpoint, three interrupt endpoints, six bulk endpoints (three input and three

output). The connector is a standard 4-pin socket (pin 1 is the bus voltage rail, 2 & 3 are

the positive and negative signals of the differential USB receiver/driver respectively and

pin 4 is ground).

Note: ensure that the current Blade software supports this interface before attempting to

use it
