我有一个 Trancsend Jetflash TS2GJF210 USB 驱动器。当我将其连接到我的旧笔记本电脑（Dell Latitude D630）时，它未安装。dmesg显示以下消息：

但是，如果我断开设备并将其连接到另一台笔记本电脑（Dell Inspiron N4010），则设备将正确安装并dmesg显示：

我尝试过多次将它连接到工作笔记本电脑 (N4010)，然后在弹出后移除 (安全移除) 并重新连接到 D630。我甚至fsck在工作笔记本电脑上运行此设备。但结果是一样的：它没有安装在 D630 笔记本电脑上。
在出现此问题之前（几分钟前），闪存驱动器在两个设备上都正常工作，但现在它已安装并仅在 N4010 上运行。
两台笔记本电脑都装有 Ubuntu 13.10，N4010 从 Ubuntu 13.04 升级并更新，D630 全新安装了 Ubunut 13.10。
我需要知道为什么会发生这个问题以及如何解决它。
