StarTech.com 4 PORT USB 3.0 HUB

This is a very well made and specified Hub. I would suggest opening the case & changing the lower board jumper from bus to external power. This will allow the hub to be freed from the constraints of bus power to using the connected PSU power. A number of low powered devices on the bus would not connect (perhaps an overload from many devices) but since this has been done the operation has been flawless. It would have suited my purpose to have been slightly shorter as I was fitting the hub into a case but other than that I have no complaints.

This is great product for extending the number of ports. You can charge lower powered devices (not ipads etc) unless you provide extra power via the additional socket. I understand that it's really intended for industrial situations and can be mounted on a din rail but doesn't look out of place wall mounted in an office. It's very well made and works well. It comes with a cable to connect to the computer and a plug for the power socket - I've not used that part. Overall 5 star. It is however extremely expensive so you would really want it over anything else.

I bought this Hub to power all my USB camera equipment for astronomy. So far, I've got 2 cameras, a filter wheel and a com port. That's a mixture of USB 2 and USB 3 devices. All plugged in and running nicely off this hub. The wide range of Input voltages means that I can power it from a leisure battery without having to worry about the exact voltage that I'm putting in. Expensive, but it's stable and seems to be reliable. (I can forget that it's there.) I'm planning on adding a USB GPS, and a USB hard drive at a later date. So 7 ports is perfect.

Had this for about a year now and seems very reliable. No dropouts or port failures

It is an extremely reliable usb 3.0 hub with a steady 50 MB/s transfer of data between 2 WD passports. Supports ports with enough juice to load it up with mobile devices, disks, and game controllers. IT works on Windows 7, not sure about Mac

Very good product. 12v input power is must for my astrophotography setting. Delivers the quality as advertised.

No adaptor, pointless !

I recommend this item if you need a real industrial grade performance. This item comes without a power adapter, which makes the perfect sense to me. For general purpose it works without a power adapter as usual passive USB HUB. To take advantage of the surge protection of this item you need to power it up. As described in the technical details you may use DC power supply from 7V to 48V, which obviously makes a difference in the cost, so the customer can choose the right one. I specifically needed an industrial grade of performance, as previously I had about a dozen of USB HUBs, but even a best one of them still "kicks out" some connected devices when I connect a Dual-Dock with 2 14GB disks in it. I bought power supply (DC 48 V, 3.5 V, 120 W). Following instructions - it took 20 minutes to connect power to this item. I am using this item for the first day, very intensively. So far - even under the extreme conditions, utilizing all 7 ports, including the Dual-Dock with 2 x 3.5" disks - no "kick outs". I bought another (4-port) StarTech.com 4-Port USB 3.0 Hub - for my other PC. Both HUBs work at industrial grade performance.

Wow, it's too band everyone can't make a product this well built. Nicely done! Built like a tank. Works great. A bit pricey, but you definitely get what you pay for. Using this in a production web cam environment with multiple cams plugged into it.

Works perfectly with multiple Segger JLink devices for embedded development.

実店舗を回ってもタフそうなハブがなかったので購入しました。電源アダプターの付属がなかったので、使っていない適当なACアダプタを首チョンパして突っ込みました。電源に関しては結構柔軟なようで、問題なく使えました。＋ー間違えたところ、パワーランプがチカチカしてPCでも認識しませんでした。気をつけまそう。（ちなみに電源なしでも認識はしました）各ポートの出力が1.5か2.4なのか商品説明の表記ゆれがありますが、体感2.4だと思います。誰か詳しく計測してください（適当 筐体はもちろん、コネクター内部もしっかりしている印象です。長く使えそうです。

Es un sin sentido que no acompañes fuente de alimentación. Se supone que es para alimentar muchos usb. Tuve que compra una
