Works either not only USB 2.0 computers or I've caught a Monday device?

I had brought this card reader, as it holds many interesting card formats. The ability SDXC cards and microSD cards (mostly SDHC) be able to read, had something. Although I have currently only a computer with more USB 2.0 port, but the two - in card reader - integrated USB 3.0 ports I would then stop and use the new computer once I have a. So at least my thoughts on this.

Now, the card reader itself is still operated with USB 2.0, but this is no problem for me, as most SD (HC / XC) cards are hardly on the theoretical 480 Mbit / s (60 MB / s) anyway ,

Unfortunately, the best connections are useless if indeed the card reader lights, but is not recognized by Windows. The same game I had tried in another Windows computer and here I had no luck. The whole thing cost me about 1.5 days work, because I wanted to leave no stone unturned.

Well, so I have the card reader, unfortunately, sent back, even if it cost only a few euros.

Many, however, were lucky as I was able to hear based on the reviews. But these people also had USB 2.0-only computer? If the machine maybe only in combination with USB 3.0? Actually, you can not be, since the terminals of the card reader and two USB 3.0 sockets are completely separate.

Too bad ... would certainly be a great device - if it would work for.
