I bought a

"MMOBIEL 4 Port USB 3.0 Data Hub voor Macbook"

It worked the first time I connected it, but now it doesn't anymore. What can be the problem?

Thanks

Let me add this: I don't use a Macbook. But, agian: the product worked when I connected it the first time

The usual is we try it on another computer. I have yet to find a hub that is only for Apples (and USB.)

If it doesn't work elsewhere it's a warranty issue.

Be sure to use the cable it came with, then another cable and finally tell us what is plugged into said hub. I have encountered folk trying to run HDDs on USB hubs and they are mostly hairless.
