目前没找到解决办法，但这U盘在window下正常，已分两个区
奇怪的是UK 13.04 VM下的XP下也正常使用

swqa1549 发表于 2013-8-31 17:19
这样也不清楚哦，Kingston DT 101 G2 4G的U盘在UK13.04 64位版下能用lsusb、lsscsi检测，dmesg查看到：
...

我觉得应该是驱动，我遇到过这样的情况优盘不显示，后来我在软件中心安装了u盘驱动，显示正常了

其他的U盘都正常自动加载的，估计是内核BUG

去软件中心找找u盘驱动应该能解决，日子长了我记不清楚我安装的是哪种驱动了，要安装专门u盘的驱动！！！

再多问一句，你的优盘在微软正常是吗？里面安装的是什么？还是用来储存的？解决不了我们发起，找论坛的别人参与解决。

在XP32，WIN8 64，VM XP 32下还有同事电脑上都正常，下午还删除了两个分区，在UK 13.04 64下sdb1很久才出来，问题还是老样子

你的问题我邀请了论坛所有的元老，版主过来看看，着优盘你是干什么用的？是储存还是安装的系统？

现在是存储用也还是同样问题，之前是安装系统用的，谢谢先，我在想芯片能识别，驱动正常，但有SCSI驱动有兼容问题，这问题网上很多类似的，没见解决的，我就是想搞定，准备调试代码的书了

希望你把u盘品牌，用途，里面安装的是什么，详细说清楚大家都来看能解决，你只是一个劲地说有问题，你贴出来的是检测记录，没有人用过所有的软件所以，你说的不清楚，还有你的分区在微软下完成的还是在uk下面，说清楚，大家才知道
