ERROR: Could not list ADB devices ( new one, not like the others)

[DamonEvil]

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

phone：xiaomi12 pro
os: windows10
scrpcy: 1.24
android version: miui13 （based on android 12）

C:\Users\Administrator\Downloads\scrcpy-win64-v1.24>scrcpy.exe
scrcpy 1.24 <https://github.com/Genymobile/scrcpy>
ERROR: Could not list ADB devices
ERROR: Server connection failed

steps before 'scrcpy':
first, I just run adb.exe usb, the result seems right, but scrcpy cannot work,

C:\Users\Administrator\Downloads\scrcpy-win64-v1.24>adb.exe usb
restarting in USB mode

then I searched a lot, run the commands as follows:

C:\Users\Administrator\Downloads\scrcpy-win64-v1.24>adb.exe kill-server

C:\Users\Administrator\Downloads\scrcpy-win64-v1.24>adb.exe start-server
* daemon not running; starting now at tcp:5037
* daemon started successfully

C:\Users\Administrator\Downloads\scrcpy-win64-v1.24>adb.exe devices
List of devices attached
7febd68c        device

the output seems right, but scrcpy still can not work , what should I do to solve this problem? Thanks a lot !

What is the result of adb devices -l?

[DamonEvil]

What is the result of adb devices -l?

C:\Users\Administrator\Downloads\scrcpy-win64-v1.24>adb.exe devices -l
List of devices attached
7febd68c               device product:zeus model:2201122C device:zeus transport_id:6

[rom1v]

OK, so it's correct, the content can be parsed correctly.

Maybe the process adb could not be executed from the scrcpy process (some antivirus/firewall or similar).

What is the result of scrcpy -Vdebug?

Maybe the process adb could not be executed from the scrcpy process (some antivirus/firewall or similar).

before I got the new phone , my last phone-xiaomi11 could be displayed and controlled normally. But I still use the same computer and security software.

What is the result of scrcpy -Vdebug?

same as runing 'scrcpy' alone

OK, I added some more logs, please replace this binary in your v1.24 release.

Also, what is the result of echo %ADB%?

[DamonEvil]

well, I just got home. I try it with my computer with windows11, it works perfectly like this:

PS C:\Users\78450\Downloads\scrcpy-win64-v1.24> .\adb.exe usb
* daemon not running; starting now at tcp:5037
* daemon started successfully
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.

Before, I tried with my laptop in company actually. I will reply you tomorrow, to see if that new 'scrcpy' works and show you the log of running command and the value of 'echo %ADB%'.

[DamonEvil]

OK, I added some more logs, please replace this binary in your v1.24 release.

I didn't add it to the system viriable

%ADB%

ERROR: read() returned -1

OK, so reading the output of the process failed. Maybe a permission issue related to the OS, if it is only on your company computer :/

[DamonEvil]

Well, I can not find any problem about the OS, so I give up. Maybe I should buy a new laptop just for work. Thanks a lot.
