CG-7PU3MGD from our MDS-UH Port Management Series is a USB3.2 Gen 1 Hub that complies with the Universal Serial Bus (USB) Specifications Revision 3.1 Gen 1 and works up to 5Gbps. It provides 7 downstream facing ports with standard A-type USB3.2 screw-lock connectors.
The CG-7PU3MGD provides a unique self-power mode to work with a wide range (+7~48V) input DC power from its terminal blocks. It supports USB charging specifications by turning its downstream ports from a Standard Downstream Port (SDP) into Charging Downstream Port (CDP) or Dedicated Charging Ports (DCP).
Since the USB is the most popular external port for the devices to connect to PCs, the CG-7PU3MGD provides an ideal solution to expand your USB ports immediately and save your investment.
The CG-7PU3MGD software package contains several managing software utilities that support different platforms allowing better control over each individual ports’ status. A GUI (Graphical User Interface) and console command prompt utilities for all major Microsoft Windows. It also includes utilities for different Linux versions. The utilities were written to easily operate with the applications software written with different language such as C#, C++, VB, Python, or even a PHP server scripting language.

Note: The last USB port of this hub (Port 7) does NOT support USB 2.0 / 1.1 devices. It is used to communicate with managing utilities. However, it still supports USB 3.2 Gen 1 devices.
*Surface Mounting screws not included.

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.
To prevent this, follow the steps below (depending on your operating system).
Windows 10 / 8
Note: You may need to disconnect and re-connect your USB device after applying these settings.
Windows 7 / Vista
Note: You may need to disconnect and re-connect your USB device after applying these settings.
Windows XP
Note: You may need to disconnect and re-connect your USB device after applying these settings.
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:
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:
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.
5 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.
