From d034a1f4577108a465e8347d11a51dc0e5a29298 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B8rn=20Mork?= Date: Tue, 19 Nov 2019 14:37:24 +0100 Subject: adb: fix for SuperSpeed devices MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The USB descriptor parsing in adb fails to detect SuperSpeed devices because of the SuperSpeed Endpoint Companion Descriptor. This cherry-picks the upstream fix for the problem. Unfortunately there never were a release with this fix before the conversion to C++, so upgrading to a newer version isn't an option. This makes adb work with SuperSpeed devices like the Sierra Wireless EM7565. Tested and verified.
