I have on a iMac 27 inch late 2014 a USB 3.0 hub. In system overview is this a usb 2.0 hub when i connect a Sandisk 3.0 cardreader. What is the problem?

Sorry that system overview is in Dutch language.

Hmm I might say that this USB is not compatible with your iMac. CMIIW

The hub appears on my Mac based on what is plugged into it. I have the UH720, and in the Mac system information it appears as two separate hubs: a USB3.0 hub with my 3.0SS devices plugged in, and a separate 2.0 hub with my 2.0 devices plugged in.

thanks for your information.
