PL-2311 USB to Ethernet

The USB-Ethernet device integrates a 802.3u fast Ethernet controller with a USB
interface for the host link. With the USB interface, a user doesn’t need to shut down
the power or remove the PC case when installing a NIC card. The us ers just simply
plug the cable into the PC’s USB port, then the 100 percent plug-n-play feature can
ease the installation effort to the minimum. In addition, the software driver provides
the NDIS interface, it is just like an ordinary NIC card utilizing the standard Windows
APIs, such as Window Explorer and Network Neighborhood. In addition to Ethernet,
the HomePNA PHY can also be connected through the provided MII interface.
