7 reviews for 12 Port USB 2.0 Powered Hub w/ Port Status LEDs

  1. Customer

    The hub is multi-tt which was essential for us because we are connecting a sound card to each port. Came with power supply, usb cable and mount plate. Perfect for mounting in a server cabinet.

  2. Robert S. Boisvert

    First Visual Observations:

    Jet Black aluminum case with integrated Wall Mount flange. Looks well constructed with rubber feet. It is constructed with (12) USB 2.0 type-A Ports and (1) USB 2.0 type-B upstream connection closest to the status LED. The CE FC compliance logo is clearly located on the bottom of the USB 2.0 hub. The hub has a three wire terminal plug for additional power with the 7-24 volt AC power supply included.


    The packaging for the hub itself surrounds the contents tightly where the hub is resting in a die cut cardboard cutout, the USB A to B cable along with the small package of mounting plates and screws are also contained in the main package.

    Product Operation:

    This product lived up to what I expected, it is a USB 2.0 12 port hub which has proved to support my USB 2.0 peripherals used with it including a PC Web Cam, (2) external hard drives, USB Mouse, and (3) USB flash drives, all used in Windows 8.1 operating system. Although I did not have to utilize all 12 USB ports my speeds were at approximately 300Mbits which is normal for high speed USB 2.0 signaling. I did not need to use the external power supply as the external USB hard drives used were Western Digital passport style; this would have been needed if I were using higher power consumption peripherals.

    Pros for this product:

    The hub looks much bigger than it actually is, it is very compact but well constructed so mounting it either on the wall or table top out of the way is great. Since the USB ports are located on the back wall of the hub, this allowed me to keep my connections much more organized. I didn’t lose information or speed of the devices while transferring any data.

    TIP: Although the USB ports are grouped nicely for connections, keeping a cable tie handy so the cables don’t end up getting caught or disorganized in some way is helpful.

    The 3 wire terminal connector is removable and only needs to be present with use of the external power supply.

    Final Comments:

    I work with several computer systems and computer peripherals every day, this hub was certainly a plus with the older USB 2.0 equipment we have in organizing our office layout. This is a good versatile hub to use with your USB peripheral management.

    Special Note: This review has not been solicited by the seller of this item.

  3. Ben Steigerwald

    These worked well for the integrated application I was building, but they are not very fast. I would only use these if you need low bandwidth USB (like USB-RS232 converter)

  4. Whitetornado

    If you are like me, with zillion USB devices at hand, you do not want to plug it all on your tower, and my experience with USB hub is not great, they are usually built so cheaply they just will not last. After a log of googling, I found that hub. 12 Ports !!! Only draw back, which is a bit silly is you have to purchase the power adapter separately and it has a special connector which you need to find, seriously, a 12 ports hub, it is an absolute must to get it powered. In anycase, once it is powered, it works flawlessly, never once I had an issue. Even with wify headphones that came with a warning that it would not work on a hub. Also great for rackmount system since it comes with the rackmount attachments. As far as I am concerned, there is no other such hub.

  5. sandinak

    So I have had this product for a few years now, and been very happy with it. I have a large powersupply connected to it and have over 8 ports used on a regular basis including kbd, mouse, trackball, several disks, printers, etc. and it Just Works. The price is not for the faint of heart, but I can say you get what you pay for in this product. My only grief is it didn’t come with a power supply. Make sure you get a good one, or scavenge an old 5VDC supply, when you purchase it.

Hubs F.A.Q.

Product F.A.Q.

View frequently asked product questions below. Still need help? Reach out!

  • Can the hub be used without a power supply?
    In some cases, yes. USB peripherals that only require low power (i.e. keyboards & mice) can be used without a power adapter. Power in this case is drawn from the host’s USB port.

    When high-power USB peripherals are used, a power supply for the USB hub may be required. In other cases, the USB peripheral may require their own power adapters, in this case, a power supply for the hub may not be required. Without ample power though, the USB hub or connected peripherals may not operate correctly. It is recommended to use an included power supply when possible.

  • After waking up from sleep mode, my computer/host no longer recognizes my USB device.
    If the USB device does not function properly after your computer or host has been in sleep mode, it is likely that Windows turned off the USB Root hub in order to save power.

    To prevent this, follow the steps below (depending on your operating system).

    Windows 10 / 8

    1. On your keyboard, press the Windows key + X and select Control Panel.
    2. Click Hardware and Sound, then click Power Options.
    3. Click Change plan settings for the plan you want to change.
    4. Click Change advanced power settings.
    5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.
    6. Click OK to apply the setting.

    Note: You may need to disconnect and re-connect your USB device after applying these settings.

    Windows 7 / Vista

    1. Click the Start button and select Control Panel.
    2. Click Hardware and Sound, then click Power Options.
    3. Click Change plan settings for the plan you want to change.
    4. Click Change advanced power settings.
    5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.
    6. Click OK to apply the setting.

    Note: You may need to disconnect and re-connect your USB device after applying these settings.

    Windows XP

    1. On your desktop, right-click the My Computer icon and select Properties.
    2. Click the Device Manager tab.
    3. Expand Universal Serial Bus controllers by clicking the arrow to the left of it.
    4. Right-click the first USB Root Hub device and select Properties.
    5. Click the Power Management tab.
    6. Clear the box next to Allow the computer to turn off this device to save power.
    7. Click OK to apply the setting.
    8. Repeat steps 4-7 for any remaining devices in the Universal Serial Bus Controllers section with “Root Hub” in the name.

    Note: You may need to disconnect and re-connect your USB device after applying these settings.

  • The hub is properly hooked up, but is not functioning correctly. What can I do?
    Testing all setup components is the best place to begin troubleshooting. To determine the source of the issue, individually test your:

    • USB Cable by using it in another setup, or trying another cable.
    • Host USB Port by connecting another device or thumb drive.
    • Connected Peripherals by connecting directly to the host.

    Moving on to troubleshooting the hub itself. Attach a USB peripheral. The USB hub itself will not appear in hardware listings on your host’s system. USB devices connected however, will appear when connected. If the connected device is still not being found, try:

    • Installing the required drivers for the USB peripheral.
    • Install the most recent drivers for the USB controller and/or motherboard chipset.

    USB hubs do not require drivers or software.

    Troubleshooting the desired USB peripheral may be in order. If the peripheral is still not being recognized, attempt:

    • Attaching external power to the peripheral, if required.
    • Confirming if the peripheral functions on a standard USB port.
    • Testing if basic USB peripherals work, such as keyboards or mice.
  • How can external power be connected to the industrial USB hub?

    External power is supplied by connecting to the terminal block located on the hub. For when an external power adapter is required check out the Accessories & Replacement Parts section on this product page. To view all of our hub accessories and power supplies, visit the category here.

    To determine the power requirements, the equation to use is P = 5 * I * N, where:

    P is the power wattage.

    is the USB port voltage.

    I is the current of the USB port in Amps (USB 2.0 is 0.5A, USB 3.0 is 0.9A.

    N is the number of USB ports.


    As an example using the equation, a 4 port hub would reflect a minimum wattage of 18 watts.

    Knowing the minimum requirement, a proper power adapter can be chosen. In this case the voltage of a power supply should be within 7 to 24 or 7 to 40 Volts DC, depending on the specifications of the USB hub. Also, the power supply must convert AC to DC (no AC output).

    Power supplies often come with a voltage (V) rating and an amperage (A) rating. To determine the current in amps, use I = P / V, where the following is true:

    I is the current of the power supply.

    P is the calculated power of the hub.

    V is the chosen voltage of the power supply

    Continuing the example, the 4 port hub requires 18 W and the power supply you choose is 12V, the current of the power supply would be I = 18/12, I = 1.5A.
