Lack of a trusty USB3.1 Hub in astrophotography market, triggered us to develop a USB3 Hub controller which will be also able to switch ON/OFF each USB port.

We proudly present the Pegasus Astro – USB Control Hub (in short UCH):

A SuperSpeed (SS), low power, switchable USB3.1 Gen1 hub and fully compliant with USB-IF’s USB 3.1 Gen1 specification . The Hub supports Hi-Speed (HS), Full Speed (FS) and Low Speed (LS). The new SuperSpeed hubs operate in parallel with the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.

6 x USB3.1 Active Ports

Device has 6 x USB 3.1 Ports. All ports are backwards compatible with USB 1.0 and USB 2.0 devices. Moreover, each port can deliver up to 2.5Amps of current. There is a smart current limit sensor in every port which automatically limits or cuts power in case of a short-wire or power consumption that is above 2.5Amps. Each port is monitored by the USB Controller and in case of a current limit, it triggers a warning popup in the operating system.

Aluminium Enclosure

A high quality robust, blue anodised aluminium enclosure houses the electronics of the USB Hub. The metal enclosure designed and tested to survive ±5kV ESD strikes.

Switchable USB Ports

Each USB port can be controlled and switched ON/OFF by our standalone software. (power + data). You are going to love this feature. No more pull out and re-plug USB cables of your equipment.

12V DC Operation

The 12V DC operation was our first design requirement. As most of your astro-equipment work with 12V DC why to use something different?

Hub accepts 12-14V of operation. This means that you can plug unregulated 12V power from a battery.

Industrial grade temperature support

Most USB Hubs in the market (well…nearly all of them) operate under room temperatures as they were design to work inside your cosy warm room. This is one of the reasons why you experience USB disconnects and instability during a cold night.

Our product is certified to work flawlessly from −40°C to +85°C. All USB Hub electronics has been selected to support Industrial grade temperature ranges.

ASCOM Switch support

Device fully supports ASCOM switch. This means that you can switch ON/OFF each USB port via ASCOM supported software.

Expansion Port (EXT)

A RJ12 external ports allows future device expansion

Standalone Software

Switch ON/OFF USB Ports on demand. Monitor USB Voltage levels. Easily name each USB port based on the device that is attached on it.

Pegasus USB Hub Software


Device is fully compatible with Microsoft Windows 10, 8, 7, XP, Apple OS X 10.4+, and Linux hub drivers.


Size: 100mm x 72mm x 24mm / 3.9” x 2.8” x 0.94”
Weight: 200g / 7 oz

Why should I get this HUB when I can buy similar 7 or even 10 port hubs for way less

A good question so please pay attention to below bullet points: to fully understand what our USB Hub can offer.

  • Each port delivers up to 2.5Amps of current. Other hubs cannot support that.
  • Switchable USB Ports. Each USB port can be controlled and switched ON/OFF by our standalone software. (power + data). Other hubs cannot do that.
  • UCH supports ASCOM switches. You can control the Hub from your imaging software.
  • Industrial grade temperature support. You will not find a hub that can operate below 0 degrees Celsius (32 Fahrenheit).

    Check specifications of each hub and you will see that operating temperature is between 0 and 40 degrees Celsius. All of these hubs are designed to work inside your cosy room and not on a mountain / outside where temperature can quickly drop especially during winter nights. If your hub works below this temperature it is by pure luck.

    Most people will experience random USB disconnects or USB bandwidth throttling during the night. These temperatures are out of operating specs for these hubs.
  • UCH can achieve very high speeds to all USB ports (simultaneously) by using multiTT (Transaction translators). Cheap hubs will reduce speed when you try to simultaneously transfer data from more than 2 ports.

    Most hubs out there have 2 or 3 similar USB chips inside (each chip is for 4 USB ports). They use one USB port to daisy chain the chip together and you have 7 or 10 ports available.

    This means that your actual speed is limited by the uplink connection between the chips. Our hub is a real 7 port branded / automotive grade USB chip (6 ports are available / 1 is used for internal communication.
  • Similar Hubs costs around USD500. You can google it if you search “USB industrial programmable hub”
