Subject: [PATCH] ADB on linux: Handle USB SuperSpeed extra Descriptors
|
||
|
|
||
|
Under Linux, ADB manually parses USB Descriptors to check for
|
||
|
possible ADB USB Interfaces. USB Devices connected with SuperSpeed
|
||
|
will exhibit extra USB SuperSpeed Endpoint Companion Descriptors.
|
||
|
This patch handles these USB SuperSpeed specific USB Descriptors.
