Failed to support desktop PCs with USB 3.2 Gen 2 ports
Does not work with my HP mini PC with USB 3.2 gen 2 ports - when connecting USB portable SSDs to the hub. You won't believe it, but many USB 3.2 Gen 2 hubs only support laptops not desktop PCs (except hubs that have dedicated power supply for higher power USB devices e.g. SSD/HDDs) when connecting USB portable SSDs to the hub. We need a major fix from many of the USB hub vendors so these products can work with desktop PCs that have USB 3.2 Gen 2 ports. Workaround: Just directly connect the USB portable SSD to the PC instead. If you need more USB ports, pick up a good old USB 3.0 hub. They're working correctly with portable USB SSDs when working with desktop PCs. (You'd need a powered USB hub if you're connecting 2 or more portable SSDs - do your own calculation: 5V - 1A per SSD/HDD).

Perfect for ROG Ally X
Want to hook up a keyboard, mouse, headset, AND external display to a ROG Ally X? This will do it and it only takes up one (USB4) port on the Ally X. Oh, and it will also provide enough power to charge the Ally and still have juice for all the other ports. Update: I’ve now tried a few USB4 hubs because I also want Ethernet which this doesn’t have. Unfortunately I’ve discovered that most of them seem to overheat after awhile and I loose connectivity on some of the ports (for whatever reason it’s always the type A ports on the hubs that fail). After letting them cool down, the other USB hubs work again, but it’s still frustrating. This StarTech hub is the only one that works for hours. It’s a little bulkier than other hubs I’ve tried, but that’s probably because it needs to be that way for proper heat dissipation?? Anyway, I wish it had a few more ports (including Ethernet), but for reliability this thing is the best I’ve found.

The Best!
This thing is amazing! Worked right out of the box. No drivers to install, no confusion, just plug and go. I'm using this hub to connect a mouse, a keyboard, and a monitor to my 2025 MacBook Air (M4). Before buying this I bought a complicated, powered hub for 2x the price and wasted multiple hours trying to get the $%^&(*& thing to work, which it never did. If you want to run a display and a few peripherals, this Startech hub is the absolute best bang for your buck.

Quality Control Issues
I want to like this dock, I really do. I purchased it with the intention of using it as a hub for my phone + usb-c external display. The pass-through charging never worked on this dock. Tried multiple cords and tested the dock with nothing plugged into any of the USB ports -- all of the power disappears somewhere onto the hub and the actual charge rate on my phone slows to a trickle. With nothing connected, it estimates >24hrs to charge from 30% to full. The plus side is that the usb ports do work, though the usb-c display went from 100% reliability to <50% within a few months of purchase. Extremely frustrating.

This is the one, buy it for DeX!
Looking for a compact USB hub to connect your laptop or Samsung DeX capable device? Buy this one! I've tried multiple similar items from name brands, and they work fine as a USB and port hub, but this one is able to support power delivery and display data through a single (capable) USB-c cable. I assume because it is noted to be capable of some combo of USB 3.2, PD 3.0 pass through and DP 1.4 alt mode. I'm not quite sure which one(s) make it possible, but it works for an HP Spectre laptop and Galaxy phone. Only improvement suggestion is to add an additional 10gb capable USB-C port in place of the three USB-A ports, but that's being super picky. Thanks StarTech for building another unique solution for connectivity challenges.
