嘗試掛載usb，但是失敗囉~

7.解決minicom亂碼問題（家用主機一樣是ttyS0）
env LANG=env_US minicom -s
*A - Serial device : ／dev/ttyS0
*E - (串口速度): 115200 bps，
8N1,
No,
No.

8.目標：順利在pxa300中mount MMC卡（32MB）
8.1.
把MMC卡放入pxa300中,不能順利mount
8.2.
於是把MMC卡用ubuntu的gparted格式化,卻沒想到越切越小（31MB到23MB）
8.3.
回到xp底下使用hp格式化工具把MMC卡還原成31MB(正常大小)
8.4.
到ubuntu的gparted工具格式化為ext2格式
8.5.
插入MMC卡的訊息：

8.6.fstab似乎不用去動他...總之成功了
