(solved)不能识别usb设备了

fallening

最近几天的事情，忽然发现找不到U盘了，以为坏掉了，于是去重新买了一个，结果还是不能用；
打开arch下的虚拟机中的xp，发现U盘使用没有问题；
下边是/var/log/errors.log的内容：

另外现在启动其慢无比，而且startx启动的系统中键盘鼠标无响应，只有用entrance（类似于kdm/gdm）启动方可使用键盘鼠标，真是太奇怪了；
难道是因为我前几天装了kdemod的原因？

fallening

另外，kdemod中使用qtmod替代了qt，如何才能卸载kdemod而不会引发混乱？
yaourt -R kdemod-complete不能搞定

升级了内核？看你的usb模块设置是不是有问题...

fallening

内核升级过了，是直接pacman的，我并没有编译，应该不会在这里出现问题的吧？

fallening

方才尝试用ipod，完全没有问题，真是奇怪了

我的errors.log里也很多这种错误，但是不影响使用

fallening

这两个u盘都是kingstone的data traveler，难道是这个原因？
不过之前的时候使用是没有问题的阿
真是太奇怪了

在Xorg.0.log中有这样几句：

2. (II) config/hal: Adding input device Kingston 2.0
3. (**) Kingston 2.0: always reports core events
4. (**) Kingston 2.0: Device: "/dev/input/event11"
5. (II) Kingston 2.0: Found x and y absolute axes
6. (II) Kingston 2.0: Found absolute touchscreen
7. (II) Kingston 2.0: Configuring as touchscreen
8. (**) Kingston 2.0: YAxisMapping: buttons 4 and 5
9. (**) Kingston 2.0: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeout: 200
10. (II) XINPUT: Adding extended input device "Kingston 2.0" (type: TOUCHSCREEN)
11. (EE) Kingston 2.0: Read error: No such device
12. (II) config/hal: removing device Kingston 2.0
13. (II) Kingston 2.0: Close
14. (II) UnloadModule: "evdev"

复制代码

这是什么问题？

solved by using sudo modprobe usb-storage
