中文

升级我的华为电话（rooted）到Android 5.1.1（cm 12.1）"USB调试" 选项呈现出邮件：

'设备处于充电模式，禁用USB调试'。

即使电缆未连接时也存在该消息。

我已经尝试过以下解决方案（但是USB调试仍然灰色）：

重新启动手机
禁用开发人员模式并再次启用禁用开发人员模式，重新启动手机并再次启用它卸下电缆并尝试所有上述解决方案

english

After upgrading my Huawei phone (which is rooted) to Android 5.1.1 (CM 12.1) the 'USB debugging' option is greyed out with message:

'Device is in charging mode, USB debugging is disabled'.

The message is present even when the cable is not connected.

I have already tried following solutions (but the USB debugging is still greyed out):

Restarting the phone
Disabling developer mode and enabling again
Disabling developer mode, restarting the phone and enabling it again
Removing the cable and trying all above solutions

我已经看过这个，以便在没有连接到右USB端口，电缆有一些问题，USB驱动程序未正确安装。 Rilwan 2016-04-01 07:10:56Z, License: CC BY-SA 3.0

港口已更改＆amp;电缆变化。昨天安装了司机，直到我升级到Android 5.1.1 Alam 2016-04-01 07:22:06Z, License: CC BY-SA 3.0

如果您更改了一个USB充电器会有所帮助吗？ user159026 2016-04-01 08:46:57Z, License: CC BY-SA 3.0

最佳答案

从数据/属性/文件夹中删除'persist.system.usb.config'文件并重新启动设备为我解决了问题。
重新启动后，设备显示启用"USB调试" 的选项。

根访问需要删除该文件。

Removing 'persist.system.usb.config' file from data/property/ folder and restarting the device solved the issue for me.
After restart, the device shows the option to enable 'USB debugging'.

Root access is required to remove that file.

最后是一个有效的解决方案！非常感谢！（在我的设备上，文件被称为“persist.sys.usb.config”。） balu 2016-07-14 05:09:48Z, License: CC BY-SA 3.0

再次跑进这个问题，不记得我上次解决它的方法，所以我开始谷歌曲，我花了很长时间才能到达这里。所以我要说它像我的魅力一样 balu 2016-10-01 22:01:55Z, License: CC BY-SA 3.0

只是一个提示，该文件由系统道具文件自动生成，这就是为什么它在属性文件夹中，修复此问题的正确方法是加以prop并删除它...通常属性线在构建中.prop ......所以...从build.prop中删除行或将值从1到0更改...打开属性文件并将其读取为文本文件，属性的值位于该文件中。 Gadget Guru 2019-04-10 01:14:14Z, License: CC BY-SA 4.0

+1它有效 Irfan Latif 2020-08-14 06:09:22Z, License: CC BY-SA 4.0

Finally a solution that works! Thanks so much! (On my device the file was called "persist.sys.usb.config".) balu 2016-07-14 05:09:48Z, License: CC BY-SA 3.0

Just ran into this problem once again and couldn't remember what I did to solve it last time, so I started googling and it took me quite a while to get here. So I'm gonna say it worked like a charm on my balu 2016-10-01 22:01:55Z, License: CC BY-SA 3.0

Just a tip, that file is automatically generated by the system prop files, that's why it is in the property folder, The correct way to fix this issue would be to lacate the prop and remove it... Usually that property line is in Build.prop ... So... Remove the line from Build.prop or change the value from 1 to 0 ... Open the property file and read it as a text file, The value of the property is inside that file Gadget Guru 2019-04-10 01:14:14Z, License: CC BY-SA 4.0

+1 It works Irfan Latif 2020-08-14 06:09:22Z, License: CC BY-SA 4.0

已经尝试过。选择“USB计算机连接”显示消息“USB现已断开连接”（即使它未连接到电缆） Alam 2016-04-05 12:50:12Z, License: CC BY-SA 3.0

@Alam发生在我身上。在遵循以下步骤之前将USB电缆插入计算机。 Andres 2016-09-20 10:19:24Z, License: CC BY-SA 3.0

Already tried that. Selecting 'USB Computer Connection' displaying message 'USB is now disconnected' (even when it's not connected to a cable) Alam 2016-04-05 12:50:12Z, License: CC BY-SA 3.0

@Alam same happened to me. Plugging the usb cable to a computer before following these steps solved it for me Andres 2016-09-20 10:19:24Z, License: CC BY-SA 3.0

插入USB电缆并转到设备的开发人员选项。您可以在那里激活USB调试，然后可以将电缆返回。它不足以仅激活开发人员选项。

Plug out your USB cable and go to the developer options of your device. There you can activate USB debugging and then you can plug your cable back in. It isn't enough to only activate developer options.

我已经尝试过，没有任何成功。 Alam 2016-04-01 07:42:53Z, License: CC BY-SA 3.0

I have already tried that without any success Alam 2016-04-01 07:42:53Z, License: CC BY-SA 3.0
