REDHAT9.0使用U盘和MP3(SCSI)之全程攻略
在REDHAT9.0中使用U盘(USB)和MP3对我这个菜鸟来说一直是个老大难.在LINUX社区中看了些贴子,介绍的不是很全面.一知半解,不能解决我的MP3的挂载问题.连好MP3和电脑,看到连接状态正常,和在WINDOWS中一样,但不能识别使用.经过摸索思考,终于如愿以偿.咱们老百姓啊,今个真高兴,真高兴呀,真高兴.嘿嘿.OK.言归正传,为学习研究之便,将过程以添加注释方式原封不动展示如下:# mount /dev/hda9 /mnt/harddiskf #这是我的WINDOWS中个F盘,FAT32格式,挂载到/mnt/harddiskf目录下
# mkdir /mnt/usb #建立USB文件夹，以便将U盘内容挂载到此文件夹做准备
# dmesg|grep -i usb #dmesg显示启动信息. 执行结果为空.没有USB设备加载信息.
# modprobe usb-uhci #以下两条命令加载USB的驱动模块.
# modprobe usb-storage #usb-uhci/usb-storage为USB的驱动模块.可用lsmod查看加载的模块内容
# fdisk -l /dev/sd? #显示U盘加载后对应硬盘上的设备文件.
Disk /dev/sda: 125 MB, 125682176 bytes #显示对应的位置为sda设备文件

# mount -t vfat /dev/sda4 /mnt/usb#MP3是fat32格式的,用vfat标示类型.我再蒙!
# cd usb #哇噻,没有错误提示耶!快进去看看!
# ls #显示文件
linuxmusic #耶,嘿嘿,哈哈.天啊,我终于看到你了.成功了!
Ok.回过头来回顾一下,几个关键所在:
root@catinsunshine root]# dmesg|grep -i usb
# modprobe usb-uhci
# modprobe usb-storage
# modprobe sd_mod
# modprobe scsi_mod
# cat /proc/scsi/scsi
# fdisk -l /dev/sd?
# fdisk -l /dev/sda4
# mount -t vfat /dev/sda4 /mnt/usb
总结.一般来说如果,连接USB,redhat 不能识别是因为驱动模块没有加载.其中最关键的四个模块为:
usb-uhci/usb-storage/sd_mod/scsi_mod.
有个小问题如下:
控制中心-->信息-->SCSI 内容显示如下.(但在USB设备里看不到内容)

老兄，要与时俱进！
这种问题到了 kernel-2.6 上就不再是问题了！ 但是我一挂我的读卡器就。。。。。
