Can I use a USB hub when I connect my Exx-Series, T5xx-Series, or T8xx-Series to my computer?
We do not recommend using a USB hub. It can cause problems with data streaming and charging of the battery. Instead, we recommend using a USB port on your computer providing charging power. These ports are usually marked with a lightning symbol.
This applies to the E54, E76, E86, E96, T530, T540, T560, T840, T860, and T865 cameras.
