用普通u盘能正常识别出来。但是用mp3播放器插上去就不行,没有反应,只显示成充电。
请问这是怎么回事。另外,我的mp3在原来的xp下会识别成2个移动磁盘,一个能用,一个是空的。

看这-v干嘛。
插入,看下dmesg|tail先啊。

另外,先确定下2个分区是什么格式的。也可能分区标识符不正确,导致问题。

额。这不像是插入后的提示啊。你dmesg|less,跳到最后。找插入的提示。

前面的,那些错误,冲掉了tail的10行限制。虽然你可以tail -n 30这样找。

这样的。

居然是直接reset就断开了哦。除开线路问题。靠这些信息,想不出其他的。供电不足?

供电不足肯定不可能。因为我以前xp的时候没有出过问题呢。
