Incorrect device name in Photos 3.0 (not iTunes)

When pulling photos and movies from multiple devices (lets call them A, and B) into Photos library, the sidebar devices-list does not shows incorrect phone (Photos shows device A while B is actually plugged in) and therefore cannot pull photos (on occasion notifies that i must unlock the 'incorrect' phone).

In iTunes, I am able to see both devices (and after i renamed the devices A to A' and B to B', then iTunes shows correct device list (via wifi connection). Now that I have renamed devices, iPhoto still shows A even if A', or B' is connected via Cable. iPhoto device does visually/audibly drop connection (disconnect) when cable removed.

Reboot devices, and restart iTunes /Photos to no avail.

All software appears to be up to date.
