fastboot和adb没有使用sudo

I have a very weird issue on my Ubuntu machine when trying to run the fastboot command.

当我试图运行fastboot命令时，我的Ubuntu机器上有一个非常奇怪的问题。

When I run:

当我运行:

fastboot devices

I get

我得到

no permissions   fastboot

So I run the command with adminidtrator permissions:

因此，我使用管理员权限运行命令:

sudo fastboot devices

And then I get the result

然后得到结果

sudo: fastboot: command not found

How can this be? I have the directory in my PATH and everything works correctly without sudo.

这怎么可能?我在路径中有目录，没有sudo，一切都可以正常工作。

Instead of forcing permissions via sudo each time you need to run fastboot, you can permanently fix the issue:

不必在每次运行fastboot时通过sudo强制使用权限，您可以永久地修复这个问题:

use lsusb to identify your device USB VendorID
使用lsusb识别你的设备USB。
configure udev to set proper permissions when your device is plugged in
配置udev在设备插入时设置适当的权限
profit!
利润!

As a bonus - it will be fixed for adb too.

作为一种奖励——亚行也将得到修正。

For example, in my case (for 'Megafon SP-A20i') :

例如，以我为例(“Megafon SP-A20i”):

$ fastboot devices
no permissions  fastboot
$ sudo fastboot devices
[sudo] password for kaa: 
MedfieldA9055F28    fastboot
$

Let's fix:

让我们解决:

First, we need to identify the device:

首先，我们需要识别设备:

a) look for usb bus number (hack: I know the device is Intel-based one)

a)查找usb总线号(hack:我知道这个设备是基于intel的)

$ fastboot -l devices
no permissions         fastboot usb:1-1.2
$ lsusb |grep 001 |grep -i intel
Bus 001 Device 044: ID 8087:09ef Intel Corp. 
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
$

b) look for other Intel devices:

b)寻找其他英特尔设备:

$ lsusb |grep 8087
Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 044: ID 8087:09ef Intel Corp. 
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
$

Hubs are not smartphones definetely, so - USB vendorID we need is "8087".

集线器绝对不是智能手机，所以我们需要的是“8087”。

Second, configure udev (you must replace "idVendor" value with yours) :

第二，配置udev(必须将“idVendor”值替换为您的值):

$ sudo sh -c "echo '# Megafon SP-A20i' >> /etc/udev/rules.d/51-android.rules"
$ sudo sh -c "echo 'SUBSYSTEM==\"usb\", ATTR{idVendor}==\"8087\", MODE=\"0666\", GROUP=\"plugdev\"' >> /etc/udev/rules.d/51-android.rules"
$ sudo service udev restart
udev stop/waiting
udev  start/running, process 1821
$

Third, re-plug your device to allow udev to perform it's magic.

第三，重新插入设备，让udev发挥它的魔力。

Final check:

最后的检查:

$ fastboot -l devices
MedfieldA9055F28       fastboot usb:1-1.2
$ adb devices
List of devices attached 

$ fastboot reboot
rebooting...

finished. total time: 0.253s
$ sleep 90
$ adb devices
List of devices attached 
MedfieldA9055F28    device

$

Voila!

瞧!
