Description

Microchip LAN78xx USB Ethernet Driver unit

The Microchip LAN78xx is a USB 3.1 to 10/100/1000 Gigabit Ethernet bridge device which supports 10BASE-T, 100BASE-TX and 1000BASE-T. Both USB 2.0 High Speed and USB 3.1 Super Speed interfaces are supported using a pair of Bulk Endpoints and an Interrupt Endpoint for signalling status changes and other events. The Raspberry Pi 3B+ contains a variant of this device called a LAN7515 which is a combination device containing a LAN78xx Gigabit Ethernet controller and two 4 port USB 2.0 compatible hubs. The hubs will be detected and bound by the default USB Hub driver when they are enumerated by the USB core.
