罗技统一接收器不再适用于所有 USB 端口

罗技统一接收器不再适用于所有 USB 端口

我有一个罗技 m525我工作时使用的鼠标(Win 7 32 位)。一开始,我会把鼠标带回家,这意味着要拔掉Unifying 接收器。但是,经过几次尝试后,我发现如果我将 Unifying 接收器重新插入之前安装的端口,它就无法工作。随着时间的推移,我实际上已经没有端口可以插入此设备了。我收到以下“USB 设备无法识别”错误:

查看我的设备管理器,我看到有一个“未知设备”:

在设备属性状态中我有以下内容:

由于该设备报告了问题,Windows 已停止该设备。(代码 43)

我尝试卸载并更新驱动程序,但无济于事。我还下载了设定点,并且之前在我第一次安装鼠标时就安装了。它仍然不起作用。我的问题有两个方面:

  1. 我有一种直觉,有残留的损坏驱动程序,因此出现“Windows 已停止该设备...”。我如何彻底删除与此设备相关的任何驱动程序?
  2. 有没有正确的方法来安装适用于 Windows 7 的 Logitech Unifying 接收器?

答案1

我也遇到了同样的问题,刚刚看了这个简单的视频在YouTube上。

基本上步骤如下:

  • 摘掉黑色帽子
  • 在里面粘一张纸,使接触点更紧密
  • 将黑色盖子盖回去

我尝试过了并且它有效。

答案2

这是 Unifying 接收器损坏/磨损的典型表现。解决此问题的唯一方法是购买另一个。但是,您必须使用罗技的软件

每台使用鼠标/新统一接收器的新电脑可能都必须这样做。虽然在全新安装 Windows 8 后,我的接收器无需任何 Logitech 软件就能很好地接收鼠标。

答案3

如果接收器无法识别,则不一定是坏了。我将 t600 接收器插入 PC(win 7 64 位),也遇到了同样的问题。我换了一台装有相同接收器的笔记本电脑(windows 8),可以毫无困难地使用鼠标。windows 7 64 位存在此问题。在声称接收器坏了或退回产品之前,请在其他设备上测试接收器。您很有可能可以修复此问题。

答案4

我很确定在 Acronis Backup & Restore 11.5 将我的磁盘映像为 .tib 文件后我遇到了这个问题。

此后,源系统和目标系统显然都缺少 C:\windows\inf\usb.inf。

我从上网本复制了它,然后“更新驱动程序”,我的罗技 k400 无线键盘又可以工作了。

这似乎不仅影响了罗技统一接收器,还影响了所有 USB 复合设备。我的 Android 平板电脑也受到影响,还有我的 Microsoft Xbox 360 USB 控制器接收器,因为它有两个与之同步的 360 垫,但我的有线 PowerA Minix360 不受影响。我的微软有线键盘 600 和罗技 V220 也不受影响,因为它们不是“USB 复合设备”,而是“USB 人机接口设备”。

USB 复合设备用于将多个子设备包装在一个父设备中,例如两个 USB 人机接口设备端点(一个用于键盘,一个用于鼠标),就像 Logitech Unifying 接收器一样。

非常感谢感谢 answers.microsoft.com 的 lucvdv 解决了这个问题

Some time ago, my system stopped recognizing some, but not all USB devices.
USB ports are fine, it reads the device descriptors but then either says
it's unknown hardware or says it can't find a driver for it.

A second symptom that must have started at the same time is that it
"forgets" all about some USB devices that have always worked fine before, 
with the same result: suddenly either "unknown" or "can't find a driver".

Two weeks ago, it was my keyboard.  
It still worked when I logged on (it had to, I used it to enter my password).
Immediately after logging on, the found new hardware thing popped up,
after a few seconds it said it failed to install my new hardware, and at
that moment my keyboard stopped working.
Never found a solution, I've been using a PS2 keyboard instead since.
I've tried other USB keyboards, it didn't recognize any of them.

Yesterday, it was the USB hub that's built into my monitor that
suddenly turned into an "unknown device", and nothing I connect
to it is detected anymore. 
In an attempt to fix that, I launched the device manager and let it
scan for new hardware.

Result: instead of my USB hub starting to work again, my 
Logitech wireless mouse stopped working. 

The "USB receiver" is now listed with an exclamation mark,
"drivers for this device are not installed".  
It worked fine just a few seconds before. 
Right now I'm back to using a wired USB mouse, but I wonder how
long that's going to keep working.

It's not the receiver that's at fault: when I plug it in,
it shows up in device management with the right name and device ID:
USB\VID_046D&PID_C52B&REV_1201 - USB\VID_046D&PID_C52B,
and status "The drivers for this device are not installed. (Code 28)".

Comparing the contents of %SystemRoot%\Inf to another Win7-64 system,
I noticed that file USB.INF was missing.
Copied it over from the other system, started device manager and
re-installed drivers for the non-working devices, and the problem is fixed.

感谢您的耐心追踪,lucvdv!
