From a34a81d120fa2c66522bfcd450003e58dae62d3b Mon Sep 17 00:00:00 2001 From: Christof Arnosti Date: Wed, 11 Mar 2020 11:33:52 +0100 Subject: android usb serial: Prepare device / driver select This commit contains the serial_android_usb part of the changes proposed in issue #2657. What's implemented: - A data structure that contains all the data that can be used to describe an usb device (including user-facing string). - A function to get a list of all attached usb devices (optionally with selectable driver class). - Changes in the serial_android_usb_open-function and in the Java part to use the information about the usb device and optionally selected driver when connecting. This commit keeps compatibility with the current UI-Code in the case that only one USB-Device is connected. If two devices are connected, only the first one is tried. There are still some small things to do: - Change the user-facing string to something more descriptive. - Parts which aren't uesd anymore when the UI-Part is implemented are simply marked as obsolete (to keep compatibility for now). But generally it seems to work.
