U2713H with MacBook Pro Mid 2015 USB Hub not working at all

Hello,

I connected my U2713H to my mac book and hoped to use the USB Hub.

Unfortunately none of the USB-Ports is working (neither bottom or side)

I tried some to the tipps I found here in the forum (e.g. disconnecting and reconnecting with reboots of all systems), but still zilch...

It seems that the connection to apple notebooks is not a recent problem, I hope in the meantime there were some efforts made to fix these issues. Any tipps?

Thanks

Christiane
