Model No. USBG-4U2ML

Description

The USBG-4U2ML Industrial 4-Port USB 2.0 Powered Hub is a High-Speed USB 2.0 hub, backward compatible with USB 1.0 / 1.1. It provides an out of the box industry standard that allows connection of up to four USB peripherals. The USBG-4U2ML Hub incorporates Diagnostic LED’s providing port status for each port and power status.

The design is compact and provides quick and easy access to connections. The Industrial 4-Port USB 2.0 hub provides four type “A” downstream ports for connection to additional USB devices, or USB hubs. A single type “B” upstream port connects the USBG-4U2ML to the host computer or another USB hub. This USB 2.0 Hub enables up to 127 devices for connection by cascading multiple hubs. Configuration of the hub is managed by the operating system once connected. The USBG-4U2ML hub operates seamlessly with both Microsoft Windows and Apple Macintosh Operating Systems.

As a standard USB hub, the USBG-4U2ML buffers USB data from any attached peripheral in compliance with USB specifications. This provides an invisible extension of the USB bus. Supporting both low speed (1.5Mbps and 12Mbps) and Hi Speed (480Mbps) devices, each port creates a bridge between the peripheral and host computer.

6 reviews for 4 Port USB 2.0 Powered Hub w/ Port Status LEDs

  1. Ong K.

    Good product

  2. E. Hansen

    Bought a couple of these. They’re not cheap but are really sturdy and work great. Had issues with every usb hub I’ve ever tried. Either it had driver issues, or needed a separate power supply, more wires to run, or was cheap plastic, or got lost on the desk.
    These mount to the underside of a desk, or the wall. They’re easy to install. No power cords. Tension on the plugs is great. No complaints at all.
    People are truly impressed at the ease and convenience when they hand over a usb drive and you plug it right into the wall. No climbing under the desk with your ass hanging out while you search for the CPU and do the USB flip shuffle.
    If you have a desk with grommets, look up the belkin grommet mounted hub, which is also cool.

  3. Rob

    in general telescope equipment runs on 12V, so i need a USB hub that could sit on the telescope itself to connect to the focuser, cameras, etc. it was easy to mount and it’s working great so far.

  4. Brian

    I wanted a hub to permanently mount in my camper van and so far it has been perfect. It was easy to install and seems to deal with the varying voltage just fine. I use it to charge my tablet and phone, and to run my USB hard drive.

  5. Kman

    Seems to be very solid and good quality. Running this in a Car PC setup with 12v. Hasn’t caused any problems yet.

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.
