I connected this via USB 3.0 and everything works without a power adapter. Am I doing it wrong? OK. The card reader confused me a bit because I thought the whole card should be inserted into the device, but that's not correct. Just insert the tip of the SD card and your computer will normally read it as a USB drive. I transferred photos from my old camera and everything went smoothly. Overall the cost is pretty decent because of all the features you get with it. I had a 4 port USB hub with only USB ports that gradually became a 1 port USB hub because the other 3 ports broke and it was about the same price. I replaced it with this one. If the same happens I will update my review.
