Very weird failure about fastboot

This failure often occurs when I use fastboot to boot TWRP.

fastboot boot ~/twrp-3.5.2_9-0-nash.img
Sending 'boot.img' (36576 KB)

There was no response at all.

At this time, I can only unplug the usb cable and reconnect it, so it seems that fastboot can work again.

There seems to be nothing interesting in the kernel log.

android-udev is of no use to me.

It appears fastboot is working fine. The issue may be with your phone or TWRP.

I would post on XDA for help as this is not an Android support forum.

In fact, I did not encounter this failure on Windows.

It’s a dependency of android-tools which contains fastboot. Is that what you have installed or did you obtain the fastboot binary elsewhere?

You can also download The Android SDK Platform Tools directly from Google and run them anywhere:

https://www.xda-developers.com/install-adb-windows-macos-linux/#adbsetuplinux

I installed android-tools from the software source.
And I tested the binary file of SDK Platform Tools downloaded from the official website of google, and both fastboot have the same failure.

The same problem. fastboot devices works and shows a device, but no other “fastboot”. Almost “clean” Manjaro stable install.
Windows on the same pc, same cable and same phone works fine.
What’s more interesting that at first it worked ok on linux, but suddenly just stopped. Total mystery.

some fastboot commands just don’t work, while it definitely works on the same machine (device, cable) on win.
