The CG-7U3CML is a 7-port Type-C USB3.2 Gen 1 Metal Hub that complies with the Universal Serial Bus (USB) Specifications Revision 3.2 Gen 1 and works up to 5Gbps. It provides 1 USB-C upstream port and 7 USB-C downstream facing ports.
With the RISC-like USB3.2 controller, the CG-7U3CML is backward compatible with any USB3.2/2.0/1.1 devices which connected to its downstream ports.
The CG-7U3CML provides a unique self-powered mode working with a wide range (+7~48V DC) input DC power from its terminal blocks and DC jack connectors. It supports fast USB charging specifications by turning its downstream ports from a Standard Downstream Port (SDP) into a Charging Downstream Port (CDP) or a Dedicated Charging Port (DCP).
Since the USB is the most popular external port for the devices to connect to PCs and mobile devices, the CG-7U3CML provides an ideal solution to expand your USB ports immediately and save your investment.

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.

Fantastic little brick for the modern era
I have about 20 USB devices connected to my computer. 4 can connect to my monitor, but I needed a lot more ports. All my cables are USB-C (to Micro B, Mini B, B, USB-C Device, etc). I try to make sure everything is always USB-C so I don’t have any issues. I have a lot of development kits, serial devices, debuggers, lab equipment, and other things connected to my computer. I could barely mamage it before, and as I scaled up I needed to make sure power could be delivered fine to all these devices. This is the perfect thing for that. I highly recommend it if you want to go full USB-C. I could not find any alternatives that offered this many ports at gigabit speeds. The only issue I have is it is a bit pricy, but I am paying hoping that in the future that more vendors will offer things like this.I also like that this can be mounted on a rail. I don’t use it that way, but if I ever decide I want to save more space on my table that would be great. I also love the screw-in USB-C cable. It is pretty cool and very secure. All the ports seem to have the ability to be secured in this way, but you only get one cable for this out of the box. I am sure that if this was used in an industrial setup or on the wall of a lab that this would be good to ensure nothing can come out or be stressed from the cable being pulled while on the wall. In any case, I recommend it, just note the price. It is well built. Just make sure if you want to power it that you bring your own DC power supply as it is not included.
