From any of several devices that I bought in the past few months, I'm more excited. If you have many devices with USB port and especially if they are supplied via USB, you just have to buy a powered USB hub. I had with him still no problems. At first I thought that 7 ports VLT too much will. Now I know that it was absolutely right. Each port can be individually enable and each is supplied with 5V and 500mA full. Just great!
