From 5fa181fb7901a56a9eece0b4f3faeea054476fec Mon Sep 17 00:00:00 2001 From: serversdown Date: Fri, 25 Sep 2026 23:27:39 -0400 Subject: [PATCH] docs(series4): confirmed -- the cable came home with the failed unit Removes the last caveat. The Benfei (Prolific PL2303) on the bench is physically the cable from the failed office setup, not a substitute picked up later. The chain has no inference left: that cable is a PL2303; the Micromate USB host has no Prolific driver in either firmware line; a laptop on the same cable and modem round-trips perfectly; the Micromate on it never answered. The FTDI cable arriving 2026-09-26 is now a confirmation rather than a test.
