The FP300 /w latest firmware going offline after some time problem is confirmed… Back to the drawing board. Finding a solution will take more time.
As warned on the dedicated driver thread - do not update the FP300 firmware for now.
Update: whoever has the latest FP300 firmware already updated, please update again manually the P1 driver - same version 2.1.3, new time stamp "2026/05/31 9:37 AM".

Update2: Unfortunately, the device went offline after 26 hours ...
