Leider kann der Hub+ nur USB 2.0 (steht in der FAQ), und wie dann der SDXC Slot durch den Chipsatz angebunden ist, ist fraglich.
Yes, you're right ;O)...
Are the USB Type A ports USB 3.0 or USB 2.0?
For Hub+, they are USB 2.0 currently because there is no stable chipset right now to support USB-C to USB-A 3.0 for a hub product. We will update the product as soon as we are able to get a stable chipset. Unfortunately, we can't make that guarantee right now as much as we'd like to.
