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.

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.

Good product

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.

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.

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.

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