Frequently Asked Questions

Troubleshooting

Industrial USB hubs offered by StarTech.com require an external power supply that connects to the terminal block on the hub.

To select a power supply, you need to determine the maximum power requirements (wattage) of the hub.

The equation you should use to determine the power requirements is P = 5 * I * N, where the following is true:

  • P is the power in watts.
  • is the voltage of the USB port.
  • I is the current of the USB port in Amps.
    • I = 0.5 A for USB 2.0.
    • I = 0.9 A for USB 3.0.
  • N is the number of USB ports.

For example, a four-port USB 3.0 hub's maximum power requirement is P = 5 * 0.9 * 4. Therefore, the minimum wattage of the power supply for the four-port USB 3.0 hub is 18 watts.

When you determine the power requirements of the hub, you can choose a power supply. The following criteria must be met when you select the power supply:

  • The voltage must be within 7 to 24 or 7 to 40 Volts DC, depending on the specifications of the USB hub.
  • The power supply must convert AC to DC (no AC output).
  • The power rating is equal or greater to the requirements of the hub.

Most power supplies come with a rating in volts (V) and amps (A). 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 (between 7 to 24 or 7 to 40 volts).

For example, if a hub requires 18 W and you choose a 12 V power supply, the current of the power supply would be I = 18/12, I = 1.5A.

When you troubleshoot issues with a USB hub, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • USB A-to-B cable

  • Computer USB port

  • USB peripheral(s)

To test your setup components, try the following:

  • Use the USB cable and USB peripheral(s) in another setup to see if the problem is with the components or the setup.

  • Use a different USB cable, USB port, and USB peripheral in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the hub, make sure that you do the following:

  • If a power adapter is included, provide power to the USB hub.

  • Attach a USB peripheral. The USB hub will not appear in any hardware listings on your system, but USB devices do appear when they are connected.

  • Install the drivers for the USB peripheral.

  • Install the latest drivers for the USB controller and motherboard chipset.

Note: No drivers or software are required for the USB hub to work with your operating system. The USB hub works independently of software and works with any operating system.

When testing your USB peripherals, make sure that you do the following:

  • If required, attach external power.

  • Confirm that the peripheral works on a standard USB port.

If the USB peripheral(s) can be detected on a standard USB port and not on the hub, do the following:

  • Use a new USB A-to-B cable.

  • Test your setup using basic USB peripherals, such as a keyboard or mouse.

  • Test using another USB port.

If the USB device does not work after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power. 

The steps below outline how to configure the USB root hub to stay on during hibernation, to prevent this from happening.
 

Windows 10 / 8

  1. On your keyboard, press the Windows key + X and select Control Panel.

  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 to re-establish the connection.

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 to re-establish the connection.

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 to re-establish the connection.

Before You Buy

It is possible to use some USB hubs without a power supply, however, doing so may prevent the USB hub or certain high-power USB peripherals from operating.  It is always recommended to use an included power supply with a USB hub when possible.

When a power adapter is not used on a hub that comes with a power adapter, power is drawn from the USB port on the computer and then divided between the ports on the hub. This reduces the power delivery to individual ports and high-powered USB peripherals, such as external hard drives, may not start.

On USB hubs that can use a power adapter, more power can be supplied to USB ports than what is possible with a single USB port.

If your USB peripherals require power adapters, they probably do not require power from the USB port and can be used on a USB hub without a power adapter. With USB peripherals that use power adapters, the USB ports on the hub are only used for data transfer and do not draw power from the hub.

USB peripherals that require low power (for example, keyboards and mice) can be used on hubs without a power adapter, in conjunction with other low-power USB peripherals. In this case, power is drawn from the computer's USB port, as described above.

Working great in my observatory

By: bill1054 - 08/02/2015
I was using a similar product which died after a year or two. The StarTech is installed on my telescope and has every port occupied. The 12v power was important for my application. Here's hoping this hub keeps on doing the job for a long time.

By: Worcspaul - 10/31/2015
Like the other reviewer I use the StarTech for astronomy. I wanted a sturdy powered hub capable of working off a 12v supply. The hub has performed flawlessly. Yes, it's more expensive than other powered hubs but worth every penny.

Needs Accessory guidance

By: ITMan01 - 05/02/2019
Want to use this product powered by the accessory terminal block. (never enough power from the connected PC....) From the tech specs it expects DC input (7-24V). What amperage would be nominal? I would buy this power adapter accessory from StarTech if it was listed.... Have to look elsewhere....

Matt, Technical Support on 5/10/2019 1:42:53 PM
Thank you for your feedback, The nominal amperage for our ST4200USBM will vary based on the voltage provided by your terminal block. While we don't sell terminal block power adapters, we do have a FAQ that provides the necessary information to calculate the required amperage: //www.startech.com/faq/usb_hubs_industrial_power_adapter#ST4200USBM

great quality, DIN mount bracket not included

By: joeyh - 02/21/2020
I've been using these for years quite happily, they are far above and beyond the build quality of typical USB hubs, and running them from 24v DC is perfect for my offgrid house. I switch terabytes of USB drives on and off on demand using one of these hubs. I recently bought a second one, and the DIN rail mounting bracket was not included. I don't know where to find a mounting bracket, and had hoped to DIN mount it.
