Permanent transfer aborts

I wanted a combination that exactly corresponds to this part. Additional USB ports and a card reader. At first glance, everything was okay. The cable should have been at the other end, but in little things I am generous. Well-liked me that only one drive is displayed, not four, as with my old card reader. It went so well until I had really a lot of pictures for the first time on the memory card. After that there was only transfer aborts. Fortunately no loss of data. After I have tried different USB slots on the PC, I see no other alternative than throwing away or returning. Fortunately the latter is time yet possible. I can only repeat my previous reviewers: Do not buy!
