From a37eb9fccdd423e4f430b0261ee78c1692b7c252 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Herv=C3=A9=20Poussineau?= Date: Tue, 25 Oct 2016 09:01:01 +0200 Subject: adb: change handler only when recognized MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ADB devices must take new handler into account only when they recognize it. This lets operating systems probe for valid/invalid handles, to know device capabilities. Add a FIXME in keyboard handler, which should use a different translation table depending of the selected handler.
