7-Port USB 3.0 Hub model CB-H18 problems

i’m a newbie ( even if I’m 70 y-old) so apologies for my maybe stupid question
I have a 7-port USB 3.0 Hub model CB-H18 that is not able to connect either my smartphone (a Samsung Note 8; it works only as a charger but no data) and my Microsoft USB headphones.
These two items work perfect when connected to the front USB port of my desktop. The OS is W10 64-bit.
Could you help me ?
