Windows 8.1 设备管理器现在显示 ACER 设备而不是 Google Nexus 7 的 Android 设备

Windows 8.1 Device Manager now showing ACER Device rather than Android Device for Google Nexus 7

提问by Sprozza

During a Windows Update this week I was presented with an optional patch titled "Other hardware - ACER Composite ADB Interface". This was part of a larger patch update, and I wrongly ticked and installed the patch. I do not own any Acer kit, but I do use ADBin wider Android development.

在本周的 Windows 更新中，我看到了一个名为“其他硬件 - ACER 复合 ADB 接口”的可选补丁。这是一个更大的补丁更新的一部分，我错误地勾选并安装了补丁。我没有任何 Acer 套件，但我确实在更广泛的 Android 开发中使用了ADB。

When I connect my tablet to the PC now it shows up in Device Manager inside a container named "ACER Device" with the title "ACER Composite ADB Interface". It is not visible to either the PC or ADB. Previously it appeared in a container called "Android Device" and worked fine. The device is a Google Nexus 7.

现在，当我将平板电脑连接到 PC 时，它显示在设备管理器中名为“ACER 设备”的容器中，标题为“ACER 复合 ADB 接口”。PC 或 ADB 都看不到它。以前它出现在一个名为“Android 设备”的容器中并且运行良好。该设备是 Google Nexus 7。

Annoyingly the patch is not listed in installed programs or installed updates, and I am struggling to try and remove it. I've already tried to uninstall the device (and drivers), but these just get reloaded when the device is plugged back in.

令人讨厌的是，该补丁未在已安装的程序或已安装的更新中列出，我正在努力尝试将其删除。我已经尝试卸载设备（和驱动程序），但是当设备重新插入时，这些只会重新加载。

How do I remove this patch?

如何删除此补丁？

If the problem persists, right-click the ACER ADB Interface and select 'Update driver...', then 'Browse my computer...' then 'Let me pick from a list...' and you should see two options for the Nexus, Google Nexus ADB Interface and another called MTP USB Device. Choose MTP and hit 'Next' to install the driver, then it should show up as a portable device on your computer.

如果问题仍然存在，请右键单击 ACER ADB 界面并选择“更新驱动程序...”，然后选择“浏览我的计算机...”，然后选择“让我从列表中选择...”，您应该会看到两个选项Nexus、Google Nexus ADB 接口和另一个称为MTP USB 设备。选择 MTP 并点击“下一步”安装驱动程序，然后它应该在您的计算机上显示为便携式设备。

To uninstall the ACER driver and remove the driver files:

要卸载 ACER 驱动程序并删除驱动程序文件：

(Re)connect your Nexus 7 to your computer. Open Device Manager (you can search for it from the Windows Control Panel).

（重新）将您的 Nexus 7 连接到您的计算机。打开设备管理器（您可以从 Windows 控制面板搜索它）。

Locate and expand an entry named "Android Device." The Nexus 7 should show up as either "Android Composite ADB Interface" or "ACER Composite ADB Interface" under "Android Device."

Make sure the current version of the Google Nexus USB driver is installed:

确保安装了当前版本的 Google Nexus USB 驱动程序：

Download the latest version of the USB driver from the Android Developer pages and unzip it on your desktop. A folder named "usb_driver" will be created.

从 Android 开发人员页面下载最新版本的 USB 驱动程序并将其解压缩到您的桌面上。将创建一个名为“usb_driver”的文件夹。

In Device Manager, locate your Nexus 7 again under "Android Device," richt-click and choose "Update Driver Software..." This launches the Hardware Update Wizard.

在设备管理器中，再次在“Android 设备”下找到您的 Nexus 7，点击并选择“更新驱动程序软件...”这将启动硬件更新向导。

Thanks for your help - I'd already tried all of what was suggested apart from the System Restore which I have now done.

感谢您的帮助 - 除了我现在已经完成的系统还原之外，我已经尝试了所有建议的内容。

I left a few other things that needed fixing, but it did restore the registry and patch state to a point before I applied the ACER patch, and I've now got things back as they were.

我留下了一些其他需要修复的东西，但它确实将注册表和补丁状态恢复到了我应用 ACER 补丁之前的某个点，现在我已经恢复原状。

I have marked this patch as hidden, so it doesn't get applied again in error.

我已将此补丁标记为隐藏，因此不会再次错误地应用它。

My Windows 8.1 PC did the automatic update which included the "ACER ADB Interface update for Windows 8.1" drivers. This happened while I was away and this afternoon when I came home I was asked to re-boot the PC to enable updates to be applied.

我的 Windows 8.1 PC 进行了自动更新，其中包括“适用于 Windows 8.1 的 ACER ADB 接口更新”驱动程序。这发生在我不在的时候，今天下午当我回到家时，我被要求重新启动 PC 以启用更新。

Since the updates were applied I have not been able to connect my Nexus 7 (2012) as a "MTP USB Device". I have spent hours trying to find a solution including doing a factory re-set on the tablet.

由于应用了更新，我无法将我的 Nexus 7 (2012) 连接为“MTP USB 设备”。我花了几个小时试图找到解决方案，包括在平板电脑上进行出厂重置。

The tablet connected successfully before I went away! That was a clue. So I did a Windows Restore to an earlier restore point. What do you know? The Nexus 7 now connected just like it did before.

在我走之前平板电脑连接成功！那是一个线索。因此，我对较早的还原点进行了 Windows 还原。你知道什么？Nexus 7 现在可以像以前一样连接。

I then checked for Windows Updates but carefully looked at what was being updated. The ACER ADB update was listed as an "additional update". I have marked it to be forgotten and then applied the other updates. So far so good.

然后我检查了 Windows 更新，但仔细查看了正在更新的内容。ACER ADB 更新被列为“附加更新”。我已将其标记为被遗忘，然后应用其他更新。到现在为止还挺好。

So after all that; try restoring your system to an earlier restore point and select not to install the ACER ADB update.

所以毕竟; 尝试将系统还原到较早的还原点并选择不安装 ACER ADB 更新。

I had the same case. I guess this problem is a conflict with Samsung Nexus vs LG nexus. Before I had used Samsung Nexus Galaxy. I am using LG nexus 5, now.

我有同样的情况。我猜这个问题是与 Samsung Nexus 与 LG nexus 的冲突。在我使用三星 Nexus Galaxy 之前。我现在正在使用 LG nexus 5。

In my case:

就我而言：

1. I found the driver files and removed those. (Device Manger - ACER ADB Interface [right click]Properties - [Tab]Driver - Driver Details)
2. I also removed the device in Device Manager.
3. Then, I scanned for hardware changes.. (the driver did install with auto by Windows 8.1)

1. 我找到了驱动程序文件并删除了它们。（设备管理器-ACER ADB 接口[右键单击]属性-[Tab]驱动程序-驱动程序详细信息）
2. 我还在设备管理器中删除了该设备。
3. 然后，我扫描了硬件更改..（驱动程序确实通过 Windows 8.1 自动安装）

At last, I can now browse the Nexus as storage.

最后，我现在可以浏览 Nexus 作为存储。

In my case, I selected "Uninstall" from Device Manager, unplugged the device, and re-connected. Windows 7 itself was smart enough to find the actual driver for it and lets me use it again.

就我而言，我从设备管理器中选择了“卸载”，拔下设备，然后重新连接。Windows 7 本身足够聪明，可以为它找到实际的驱动程序并让我再次使用它。

On your device, make sure that the USB computer connection is set to “Media device (MTP).”

在您的设备上，确保 USB 计算机连接设置为“媒体设备 (MTP)”。

Touch Settings > Device > Storage. Then touch Menu Menu > USB computer connection. MTP should be selected by default, but you may have to uncheck MTP, check and uncheck Camera (PTP), and then recheck MTP.

In my case, neither updating the driver nor a windows system restore help. When I tried with a different USB cable, the system detected my Nexus 5 device. For some reason the other USB cable while charging the phone does NOT show the device at all even now.

就我而言，更新驱动程序和 Windows 系统恢复都没有帮助。当我尝试使用不同的 USB 电缆时，系统检测到我的 Nexus 5 设备。出于某种原因，即使现在为手机充电时，另一条 USB 电缆也根本不显示该设备。

PS: I wanted to try with a different USB cable than the one I had but unfortunately could not get hold of one, wasted close to two hours trying all other possible solution.

PS：我想尝试使用与我现有的 USB 电缆不同的 USB 电缆，但不幸的是找不到一根，浪费了将近两个小时尝试所有其他可能的解决方案。

In my case, rolling back the driver for "ACER Composite ADB Interface" (which appeared under something like "ACER device") did the job. Right after rollback, without reboot, Nexus 7 appeared both in Device Manager and in File Explorer as Nexus 7.

就我而言，回滚“ACER 复合 ADB 接口”的驱动程序（出现在“ACER 设备”之类的东西下）完成了这项工作。回滚后，无需重启，Nexus 7 在设备管理器和文件资源管理器中都显示为 Nexus 7。
