2 reviews for 4 Port USB 2.0 Over IP Network Device Sharing Hub w/ Screw-Locking Ports & Status LEDs

  1. SSDguy

    Allows you to have USB support from your virtual machines (I run VMware ESXi Hypervisor), from anywhere in your home network.

    So in other words, if your hypervisor machine is buried in your basement, you can have this unit up in your office, and have devices like scanners, printers, flash drives etc, plugged in at your desk and access your VM over remote desktop on your laptop to make it seem like that pc is right next to you.

  2. killalot4000

    First off, you need some networking experience to work with this device.

    The device is pretty straight forward. I am using it for external hard drives to access them over the network from multiple computers. Also, you have to have the device in the same subnet to be able to use the server. Install the software was easy to do. The server tells you to use windows device removal feature and then stop the device. The device sometimes wants to crash for some reason sometimes. If you just stop all transfers on the device and use the servers manager program to remove the hard drives, it will just give a warning saying that could lead to data loss if transfers are currently active etc, and seems to work a lot better with the server.

    Am able to get about 20-50 MBps transfer, which is typical for usb 2.0 speeds over the gigabit network that I have them on. Once I fill up the hard drive using esata which is faster, I just put the drives on the usb server and access them when need stuff off them, so speed is not really a priority.

    Mounts devices to your computer as if they were plugged into your computers usb port. This device will work with printers and cd-rom which i have not tried, but have tried usb sticks which work fine. The true name of the hard drive does not show up in the manager, which can make for tricky guessing of which drive is which. The true name will show up once you mount the hard drive to your computer though.

    You are able to set passwords for the usb servers, tell it to use dhcp due to the server itself needs a ip address to be able to share drives. You can manually assign ip addresses also if need to. There is idle timeouts also. I tried to put a usb hub into the server, it will detect it, but will not work with them for some reason. Not all devices are supported by the server. This covers the main things that I have looked over that I need to use.

    May cost more and was hesitant at first as having never used a device like this before, but well worth the money. The device didn’t have no reviews either, which made left me hoping that wouldn’t be a disappointment. Will be ordering more of these devices.

Product F.A.Q.

Product F.A.Q.

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

  • My system Blue Screened. What can I do to fix this?
    In rare cases, it has been noted that the network sharing software may cause Windows 10 & 11 systems to Blue Screen.

    If you experience this issue, please follow this short guide to remedy the situation.

  • 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.
