I bought the hub for connecting a 1TB 2.5 '' hard disk to my Fritz box. However, it does not provide enough power to sterten to the hard drive. The smaller 160GB drive that actually worked directly at the Fritz box (supplies 500mA) will not start if it is connected to this hub. Consequently, the stroke appears even less than to provide 500mA to the USB specification. Conclusion: electronic waste! This part goes back immediately.
