Following the readme guide to connect device, but the error raise when connect to device. Link

I can reproduce this every time, and never get sucess connect.

My code is

from adb_shell.adb_device import AdbDeviceTcp, AdbDeviceUsb

from adb_shell.auth.sign_pythonrsa import PythonRSASigner

keygen('./adbkey')

adbkey = './adbkey'

with open(adbkey) as f:

priv = f.read()

with open(adbkey + '.pub') as f:

 pub = f.read()

signer = PythonRSASigner(pub, priv)

device = AdbDeviceUsb()

device.connect(rsa_keys=[signer], auth_timeout_s=0.1)

Same thing here. I solved killing the shell with ./adb kill-server after seeing this issue

that really matters, "adb kill-server" is not a elegant way
