1、編輯mdev配置檔案/etc/mdev.conf,新增如下語句
sd[a-z]*[0-9] 0:0 0660 @(mount -t vfat -o iocharset=
cp936 /dev/$mdev /mnt/udisk)
sd[a-z]*[0-9] 0:0 0660 *(umount /mnt/udisk)
2、核心配置,核心需要支援fat檔案系統
file systems --->
dos/fat/nt filesystems --->
<*> msdos fs support
<*> vfat (windows-95) fs support
(437) default codepage for fat
(iso8859-1) default iocharset for fat
-*- native language support --->
(cp437) default nls option
codepage 437 (united states, canada)
simplified chinese charset (cp
936, gb2312)
ascii (united states)
nls iso 8859-1 (latin 1; western european languages)
device drivers --->
scsi device support --->
scsi device support
scsi disk support
[*] usb support --->
<*> support for host-side usb
usb mass storage support
realtek card reader support
make -j4 #這樣才會編譯模組
#"-j4"4執行緒,一般幾核心cpu則-j後面就是幾。這樣可以加快編譯速度
3、載入驅動,熱拔插realtek讀卡器需要的驅動模組,建議按照下面順序載入
mount -t nfs -o nolock 192.168.0.101:/develop /mnt/develop
insmod /mnt/develop/project/linux-3.1.6/fs/nls/nls_cp
437.ko #下面4個驅動模組系統字元編碼支援,
insmod /mnt/develop/project/linux-3.1.6/fs/nls/nls_
cp936.ko
insmod /mnt/develop/project/linux-3.1.6/fs/nls/nls_ascii.ko #不是必須
insmod /mnt/develop/project/linux-3.1.6/fs/nls/nls_iso8859-1.ko #不是必須
insmod /mnt/develop/project/linux-3.1.6/drivers/scsi/scsi_mod.ko #usb磁碟在linux中被當作scsi裝置
insmod /mnt/develop/project/linux-3.1.6/drivers/scsi/sd_mod.ko #很多人都忘記這個模組,讀卡器必須
insmod /mnt/develop/project/linux-3.1.6/drivers/usb/storage/usb-storage.ko #usb儲存器驅動
insmod /mnt/develop/project/linux-3.1.6/drivers/usb/storage/ums-realtek.ko #realtek讀卡器驅動
我的飈王讀卡器(用的realtek晶元方案)例項
usb 1-1: new full speed usb device number 11 using s3c2410-ohci
scsi8 : usb-storage 1-1:1.0
scsi 8:0:0:0: direct-access generic- multi-card 1.00 pq: 0 ansi: 0 ccs
sd 8:0:0:0: [sda] 15646720 512-byte logical blocks: (8.01 gb/7.46 gib)
sd 8:0:0:0: [sda] write protect is off
sd 8:0:0:0: [sda] no caching mode page present
sd 8:0:0:0: [sda] assuming drive cache: write through
sd 8:0:0:0: [sda] no caching mode page present
sd 8:0:0:0: [sda] assuming drive cache: write through
sda:
sda1
sd 8:0:0:0: [sda] no caching mode page present
sd 8:0:0:0: [sda] assuming drive cache: write through
sd 8:0:0:0: [sda] attached scsi removable disk
此時讀卡器上的sd卡已經掛載到了/mnt/udisk目錄
4、解除安裝讀卡器
umount /mnt/udisk或者umount /dev/
sda1
注意:要執行rmmod命令必須先執行如下命令
mkdir -p /lib/modules/`uname -r` 0
