Can not connect to device with leading space in device serial number

[CameronBanga]

• I have read the FAQ.
• I have searched in existing issues.

Environment

• OS: macOS
• scrcpy version: [e.g. 1.24]
• installation method: brew
• device model: Glorystar GAD-101
• Android version: 5.1

Describe the bug
See issue #3534 (comment) for further information.

While trying to connect using scrcpy, I get the following:

scrcpy 1.24 <https://github.com/Genymobile/scrcpy>
2022-10-14 14:33:40.022 scrcpy[12626:145516] ERROR: Could not find any ADB device
2022-10-14 14:33:40.415 scrcpy[12626:145515] ERROR: Server connection failed

As determined by @rom1v, this is due to my device serial number starting with a leading space:

Downloads|⇒ adb -s GS101200400611 shell echo ok
adb: device 'GS101200400611' not found

Downloads|⇒ adb -s ' GS101200400611' shell echo ok
ok

Thank you for the report.

I started to work on supporting serial with spaces. I thought it was easy: adb devices uses a tab separator between the serial and the state, but adb devices -l uses spaces, so a space in the serial is theoretically indistinguishable from a separator. We could make a special case for leading spaces, but it seems odd :/

If it helps anyone who happens to stumble upon this, as an interim fix, I have the following script that resolves issue. Have to run again after a power cycle though:

#!/bin/bash

adb root
adb shell 'echo -n "WhateverSerialNumberYouWantHere" > /sys/class/android_usb/android0/iSerial'
adb kill-server && adb start-server

# After Completing, you need to unplug and then re-plug in your USB cable to device.
