What Should I Consider when Buying a USB Hub?
USB Hub refers to a device that can expand one USB interface into multiple and enable these interfaces to be used simultaneously. USB HUB can be divided into USB2.0 HUB, USB3.0 HUB and USB3.1 HUB according to its USB protocol.

- USB Hub refers to a device that can expand one USB interface into multiple and enable these interfaces to be used simultaneously. USB HUB can be divided into USB2.0 HUB, USB3.0 HUB and USB3.1 HUB according to its USB protocol.
- First, the word is divided into two parts: USB and hub.
- First, USB is the abbreviation of English Universal SerialBus, and Chinese is "
- 1. USB-HUB is a device that provides extended communication. If the Hub can drive a 2.5-inch mobile phone without an external power supply
USB HUB slows down

- USB-Hub is just a tool to extend the USB interface. To put it bluntly, it is just an interface extension tool. In fact, the use of USB-Hub only makes the speed of USB devices slower, and it is absolutely impossible to make them faster. The best way is to connect the USB device directly to the computer's USB interface, rather than the USB-Hub. Especially for mobile hard drives, don't try to use USB-Hub to connect easily, this will even damage the life of your mobile hard drive.
- You don't need to pay attention to this prompt, because this is likely to be caused by insufficient USB-Hub power supply. Even if you change the other socket, it doesn't work better. In addition, do not connect the USB-Hub to the mobile hard disk. Some, such as cameras, are more suitable for the USB-Hub. Do not connect too many devices to the USB-Hub, it is better to connect directly to the computer.
USB HUB mobile hard drive

- Answer: In short, the power supply of the mobile hard disk is insufficient. The mobile hard disk is powered by USB. Generally, the mobile hard disk is a notebook hard disk, with 0.5A to 1A. The smaller the current, the lower the USB power supply requirement, and the higher it is. The USB Hub itself does not supply power, and it borrows 5V from the motherboard USB. You know it. If you don't recognize it, it means that the power supply is insufficient. You can plug the mobile hard disk directly into the motherboard and use it.
- You can try to choose a hard disk with a small working current, and then buy a good quality USB Hub for a notebook, and the problem is mostly solved.
- VIA Releases World's First USB 3.0 Hub Controller
- VIA Labs, Inc., a subsidiary of the IA Group, today announced the launch of the world's first Hub Controller to support USB 3.0, " VIA VL810 ", using a self-developed single-chip design solution.
- VIA VL810 provides one uplink interface and four downlink interfaces , all supporting SuperSpeed USB 3.0 5Gbps, and also backward compatible with Hi-Speed USB 2.0 480Mbps, Full-Speed USB 1.1 12Mbps, Low-Speed USB 1.0 1.5Mbps.
- The controller chip was first manufactured using 80nm COMS technology , which has lower power consumption and also supports power management functions . It can enter a low power consumption and energy-saving state when the connection is idle, and it allows the device to communicate with the main controller for time delay.
- VIA will showcase this USB 3.0 Hub controller solution at CES 2010. [4]
