USB Hub refers to a device that can expand one USB interface into multiple ones and enable these interfaces to be used at the same time. USB HUB can be divided into USB2.0 HUB, USB3.0 HUB and USB3.1 HUB according to its USB protocol.
USB2.0 HUB supports USB2.0, with a theoretical bandwidth of 480Mbps; USB3.0 HUB supports USB3.0, backward compatible with USB2.0/1.1, with a theoretical bandwidth of 5Gbps; USB3.1 HUB supports USB3.1, backward compatible with USB3 .0/2.0/1.1, the theoretical bandwidth is up to 10Gbps Hub is a hub that we often say, it uses a star topology to connect multiple USB interface devices.
USB Hub, can be connected to computer desk lamp, computer fan, MP3, U disk, recorder, digital camera, etc. It can expand one USB interface into multiple USB interfaces that work independently. USB to Ethernet is a highly integrated, ultra-low power consumption, single-chip USB2.0 to 1000/100M Ethernet control circuit.
Adds low-cost, small package, plug-and-play Fast Ethernet functionality to a variety of applications, such as desktops, notebooks, ultraportables, tablets, bays/port replicators/docks, gaming consoles , smart home and any embedded device with USB interface.
Internally integrates a USB 2.0 transceiver, a 1000/100M Ethernet module based on IEEE802.3 and IEEE802.3az-2010, and an efficient memory control module. SR9900 is fully compatible with NDIS5, NDIS6 (IPv4, IPv6, TCP, UDP) Checksum feature. And support IEEE802IP2 layer priority coding, and IEEE802.1Q virtual local network (VLAN).
