Transcend USB 3.0 4-Port Hub TS-HUB3K, Black

100% Compatible with Raspberry PI 2. Will power the Pi and anything attached to it. I like the fact that it is usb 3... if I need it for something other than Pi or if Pi gets an upgrade...its ready! NOTE: If you try to power the pi and the hub separately: If you power on the hub 1st the Pi will not boot. If you boot the Pi 1st or power the Pi off the hub everything works as you would expect. If you do not have a USB to Micro Usb cable it would be a good idea to get one. Also the hub is slightly smaller than the Pi the 2 fit nicely together.

Installazione istantanea, ottimo per duplicare le porte USB. Lo uso per connettere la tastiera e degli auricolari con presa USB da mesi, è sempre funzionato benissimo

Uno dei più compatti e di qualità garantita. fornito anche di piccolo alimentatore con presa americana ma corredato di un adattatore di qualità in confezione separata. Funziona a dovere con Mac

this usb hub works well with windows 8.1 and have allowed for me to connect multiple devices to my computer as well as multiple printers as well

I bought this hub to use with my tablet, mobile phone, battery tank, etc.., to avoid carrying out all the chargers for each device when I am travelling, but also to use it as a dock station for my tablet when I am at home. The quick charge port charge my thinkpad 8 in reasonable time, and also work as hub with the Y cable (a cable for this specific tablet to use the usb port to charge and to connect a device at the same time). No problem if I use all the ports with all kind of gadgets (keyboard, mouse, usb 3.0 memory, usb 3.0 ethernet adapter, hard disk 3.0, an extra usb 2.0 passive hub, etc.). The device is able to work without the external power supply too, of course we have to be aware that some devices requires more power like hard disks, but I haven't had problems. I tried also to connect the Y cable to power the tablet and at the same time to use the hub, and although it works for a few seconds, it is very unstable and keeps loosing connection to the devices (probably due to lack of power), just for curiosity, actually I prefer to connect the Y cable to the tablet charger and leave a port free to use with other devices. I have used it for two months, if somebody ask me I would recommend this product.
