This directory contains the first-pass Retevis L71 ADB WinUSB INF.

Observed L71 USB hardware ID:

USB\VID_0E8D&PID_201D

The installer attempts:

pnputil /add-driver drivers\l71\*.inf /install

Driver installation requires administrator rights. If Windows rejects the INF
because it requires a signed catalog, capture the exact Windows Hardware IDs from
Device Manager so a signed driver package can be produced.
