Stick burns a lot of energy, which many USB ports can not. Receive relatively ok.

Had now found me also this stick.
On my PC, I was at first quite satisfied with the first test. The reception quality and speed was in the average score in HSDPA at about 8-9Mbit. 2 bar - with my Speed ​​Stick 2 is all better, but the cost significantly more.
Then I wanted to use the stick on a laptop. After connecting the drive to the USB Hub pulls the laptop from the entire stream, so that all devices + stick until I logged off the stick away again. Even I could through the large power consumption not use extension :( I have then taken a USB hub with power supply ago. There, the stick was then 1-2 minutes was quite warm and a lot of the USB hub from. Lived after deducting the Sticks the USB hub and the other devices it on again. I also appreciate here overload. Normally, I would think that the device is defective. However, here tell more people about this problem. For me the stick now goes back and I have the E3131 ordered, as this should be better.
