罗技无线鼠标问题

罗技无线鼠标问题

我最近购买了一台新的东芝笔记本电脑和罗技 M510 无绳鼠标。我在笔记本电脑上运行 Mint 13。

最初(至少一次)鼠标工作得很好。然后它就停止工作了。我在各个论坛上进行了搜索,发现了类似问题的报告和各种建议的解决方案。解决方案之一是在启动之前关闭鼠标并从笔记本电脑上取下加密狗。然后登录。等待(至少)10 秒,然后打开鼠标并插入加密狗。

这似乎在大多数情况下都有效,但至少有一次失败了。

我看过一个帖子(David Gatrell,2012-06-23),大意是

“这实际上更像是 bug #958174 的重复,该 bug 仍然处于开放状态。”

但据我所知,自给定日期以来,此错误没有任何“活动”。我不确定这是否适用于 Mint 13(或仅适用于“真正的”Ubuntu(12.04?12.10?)。

有人知道如何从这款无绳鼠标中获得可靠的性能吗?

答案1

在 Ubuntu 12.04 下,鼠标最初可以工作。然后就变得不稳定了。然后它又开始工作了。在 Mint 13 下,鼠标似乎仍然不稳定。我相信对于 Ubuntu,该问题已通过更新解决,可能是 linux-image-3.2.0-31-generic-pae 3.2.0-31.50。查看 kernel.org 的上游,内核版本 3.2.31 稳定版的发行说明中有以下提交:

HID: Fix logitech-dj: missing Unifying device issue

commit 596264082f10dd4a567c43d4526b2f54ac5520bc upstream.

This patch fixes an issue introduced after commit 4ea5454203d991ec
("HID: Fix race condition between driver core and ll-driver").

After that commit, hid-core discards any incoming packet that arrives while
hid driver's probe function is being executed.

This broke the enumeration process of hid-logitech-dj, that must receive
control packets in-band with the mouse and keyboard packets. Discarding mouse
or keyboard data at the very begining is usually fine, but it is not the case
for control packets.

This patch forces a re-enumeration of the paired devices when a packet arrives
that comes from an unknown device.

Based on a patch originally written by Benjamin Tissoires.

Mint 13是否应用了这个补丁或者升级到了这个上游内核还有待调查。
