    I am an amateur astronomer/photographer. I have an older laptop with USB2.0 capability with Windows 7 which I take to the outdoors for observing trips. I need 5 USB 2.0 connections to connect my camera and scopes to the laptop which only has three ports. The powered 2.0 USB Hub I got worked perfectly, whereas my other non-powered hubs did not. I'm very pleased with this product, and now am waiting for the rain to stop so I can get out observing.

    This is a very handy little USB Hub. The hub is very easy to setup. I simply connected it using the included USB cable and was up and working right away. If you have several devices plugged into the hub at the same time, it may be necessary to use the optional AC power cord. Because I use the hub mainly for USB flash drives and a memory card reader, the power cord is not necessary. The hub is very compact so you’re able to put it just about anywhere. The single port on the back of the unit is handy if you have a device with a cable that you don’t want sticking out over your desk. You can attach it to the port in the back and hide the cable behind your desk. The only downside to this hub is that because it is so small and light, the rigidness of the new USB cable that it came with lifted the hub from the desk slightly. To fix this I stuck a small piece of double sided tape to the bottom of the hub and now it sits flat on the desk. Overall I have not had any issues with the hub over several months of use and recommend it as an option for anyone who needs a couple more USB port on their computer.

    PROS: Very Small Footpritn
    CONS: None specified
    We buy these for use with Raspberry PI and BeagleBone Black projects. The enclosures come off easily and the board inside is tiny and easy to fit into a small enclosure. From the 10+ purchased to date we have had no failures.

Q: What’s the difference between the different USB versions?

  • USB 1.1
    • Released in 1998
    • Specifies max data rates of 12 Mbit/s (Full Speed)
    • Mostly used on devices such as keyboards, mice, joysticks, printers, scanners.
    • Still used by some devices that don't need faster data transfer rates.
  • USB 2.0
    • Released in 2000
    • Specifies max data rates of 480 Mbit/s (Hi-Speed)
    • Compatible with USB 1.1, but some hardware designed for USB 2.0 may not work with USB 1.1 host controllers.
  • USB 3.0
    • Released in 2008
    • Specifies max data rates of 5 Gbit/s (SuperSpeed)
    • A January 2013 press release from the USB group reveals plans to update USB 3.0 to 10 Gbit/s to put it on par with Thunderbolt by mid-2013.

Q: What is "hot-swapping?"

A: One of the best features of USB is that it is hot swappable. This means you can walk up to a computer, plug in a new device using USB, and use it right away. Most connectors on computers can only be plugged in when the computer is off. This prevents electrical shorts or glitches that can cause damage. USB doesn't have this limitation.

Q: What is "plug and play?"

A: Plug and play refers to the ability to use a new peripheral without going through an elaborate configuration process. USB is well suited for plug and play operation. No jumpers need be set or ID's selected. There are no interrupt conflicts or other messy configuration issues involved in using USB devices.

Q: What’s the difference between powered and non-powered hubs.

A: One feature of USB is that the cables distribute power as well as data. This means that devices that use modest amounts of power don't need separate power supplies.

Still, the amount of power distributed over USB is limited. An unpowered (or self-powered) hub uses some of the power coming to it for its own operation, and passes the remainder along to devices plugged into it. This is OK for small hubs with low power devices plugged into it. A good example is this is a keyboard with a powered hub built-in. This has plenty of power for plugging in a mouse or track pad.

Powered hubs have their own power supplies and can supply full power to all the devices that can physically plugged into them. Of course, you do have an extra wire and power block plugged into the wall.

Some hubs can operate either way. If they don't have their power supply plugged-in, they operate as an unpowered hub - with a limited ability to power additional USB devices. When you plug-in their power supplied, they function as powered hubs.

Q: How do I daisy chain my USB devices?

A: If you have a single USB port on your computer and need to use three USB devices, you need to first plug a hub into the computer. The hub will then have four, or seven (or however many) ports available for you to plug in additional devices.

Hubs can be daisy chained, to provide even more USB ports.
