The Kodak Instant Dock Plus does not support USB at this time. The docking pin is pre-installed with USB C-type and comes with a lightning connector for iPhones. The only other option at the moment would be connecting your smartphone via Bluetooth. It is compatible with any Android devices with versions 4.2 and above, or any iOS mobile devices with versions 8.0 and above via Bluetooth.
If you have any issues with connecting your smartphone to the device, please let us know by Submitting a Request to our team.
If not, you are good to start printing your photos!
