Model No. USBG-4SU2MLA



The USBG-4SU2MLA is a Metal 4-Port USB 2.0 Hub that complies with Universal Serial Bus (USB) Specifications Revision 2.0 and work up to 480Mbps. It provides 4 downstream facing ports with standard A-type USB 2.0 connectors. It also supports screw-lock features for both upstream (USB type A) and downstream (USB type B) connectors with the screw-lock USB cables. It prevents from disconnecting the USB cables accidentally.

With NEC uPD720114 USB 2.0 controller, it works backward compatible either when any one of downstream port is connected to an USB 1.1 compliant device, or when the upstream port is connected to a USB 1.1 compliant host.

The USBG-4SU2MLA metal 4-Port USB 2.0 hub also provides a unique feature to work in the bus-powered mode without an external AC power adapter. It’s very convenient for light power consumption USB devices to work in this mode without an extra power supply. Simply plug and proceed to transfer data. Otherwise, the external DC jack is used for self-powered mode if you need more power on the 4 downstream ports.

Since the USB is the most popular external port for the devices to connect to PCs, the USBG-4SU2MLA provides an ideal solution to expand your USB ports immediately and save your investment.

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.

2 reviews for 4 Port USB 2.0 Powered Hub w/ Port Status LEDs & Screw Locking Ports

  1. Jeff Kackley

    Unfortunately This Does Not Charge Devices if Not Connected to a Computer
    This is a nice hub. I specifically bought it because of the metal ears on it that allow mounting it with screws. I actually wanted to charge some USB devices with this and I figured since it had it’s own power source that I could do that without plugging it into the USB port of a computer. Unfortunately though if the USB is not plugged into a PC then it will not charge your devices even if the hub itself is plugged into AC power. Once you plug the USB into a PC however then charging will occur. So if you just want to utilize this as a charging station PC free then don’t get this one, instead look for their other device model CG-UC4AQC3.When used for it’s actual intention, as a USB hub, it works great. It’s a solid metal case and the mounting ears are great. It was just my mistake assuming I could power devices without a PC.

    Pricey, but worth it
    I bought this for the purpose of mounting underneath a desk top. It looks fantastic. My only complaint is that the USB ports are now upside down. It would be nice if there was a variant of this that was designed for under-table mounting.It does not come with screws. I had to buy those myself at Ace Hardware. For those who don’t plan on sticking it anywhere for good, it definitely has a fair amount of heft to it, so it won’t move around even with a thick USB cable and power adapter connected.
