Pegasus Astro USB Control Hub

Pegasus Astro has developed this useful USB 3.1 Hub controller, which enables you to switch each USB port ON/OFF. 

A SuperSpeed (SS), low power, switchable USB 3.1 Gen1 hub 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. 

Supported by Pegasus Astro Unity Platform standalone software. It also supports ASCOM 6 and INDI. 


  • 6x USB 3.1 Powered Ports
  • Each USB port can be controlled and switched ON/OFF by Pegasus Astro's standalone software (power + data)
  • All ports are backwards compatible with USB 1.0 and USB 2.0 devices
  • Each port can deliver up to 2.5Amps of current
  • A smart current limit sensor in every port automatically limits or cuts power in case of a short-wire or power consumption above 2.5 amps
  • The USB Controller monitors each port, and in case of a current limit, it triggers a warning pop-up in the operating system
  • Industrial-grade temperature support from −40°C to +85°C
  • The 12V DC operation (accepts 12-14V). 
  • RJ12 external expansion ports allow future device expansion
  • High-quality, robust aluminium Enclosure

A little blue beauty
22 March 2024  | 

I have finally bitten the bullet and ordered a specific astronomical usb hub. After several years of broken connections I now have a constant connection and greater ability to control each usb output. Alovely piece of kit that I expect to last and give better connections.

Almost Perfect
15 August 2022  | 

It was time to move away from flakey USB hubs purchased on Amazon and buy this. The Pegasus Astro USB Control Hub is a powered USB switch, with 6 x USB 3.1 ports in a rugged metal case. If you need to run devices at full 3.1 speed with power, outside, then this box is perfect, or almost. There are some things to be aware of... Firstly, it is powered, and without DC power it is a brick that does nothing, it won't even allow unpowered USB 2 devices to talk. So lesson 1 is buy this with a suitable 12v supply as extra (and the Pegasus Astro PSU can drive it at 10amps, which is more than enough). The second lesson is that this needs ASCOM 6.6 on your laptop if you want to manage it, so you might need to upgrade your software too. I did, it only took a minute, and I'm really pleased to say that not only does the custom Pegasus Astro software work but also NINA does too. NINA can monitor all 6 ports, turn them on and off, and report their power draw. Nice. The final lesson is that mounting this unit to your rig could be better - there are two tiny holes in the base, barely big enough for anything. I would love to see four standard side threaded holes to bolts. So the only practical way to mount it is with either Velco or cable ties.
