Hi @Ciprian30, let me see if I can help out here!
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
Xperia XZ2 do have support for OTG Host, which means that you can connect USB devices to your Xperia device using a USB OTG (On-The-Go) cable. In order for it to work you might need to reboot the phone with the OTG cable and the USB device attached during the boot sequence.
Try this and let me know how it goes!
