USB Mass Storage support

这些就是所以和配置使用我的HP CD-Writer Plus 8210e刻录机有关的选项。我用的是V2.4.0-test8的内核。
编译的时候会有大量的编译调试信息，如果正常的话他们可以不管他们，但如果发生问题的时候，他们可以帮助你查找的原因。
再次警告：如果你对配置和安装新内核不是很熟悉的话建议要当心，这样是有一定风险的。

1.3.2安装模块
当你的新内核和模块编译完成后，你会在modules目录下面发现下面这些模块文件：
cd /lib/modules/2.4.0-test8
cd kernel
ls fs/isofs
isofs.o
ls drivers/cdrom
cdrom.o
ls drivers/scsi
scsi_mod.o sd.o sg.o sr_mod.o
ls drivers/usb
storage usb-uhci.o usbcore.o
ls drivers/usb/storage
usb-storage.o

重新启动！

1.4 下面的步骤
下载usbmgr包，解压缩并阅读README文件。在解压后的目录里用make进行编译。然后make install。现在我们配置usbmgr的
配置文件usbmgr.conf，它放在/etc/usbmgr目录下。编辑这个文件，进行下面几步：
a) 去掉在HOST CONTROLLER这节里面的某个host选项前面的注释符"#".在我的计算机上是这样设置的: host usb-uhci
b) 把下面三行加到STORAGE一节里的vendor 0x3f0 product 0x107这个模块的最后。
scsi_mod, sr_mod, usb-storage
现在你要运行"update_usbdb"这个命令：update_usedb usbmgr.conf
接下去运行"usbmgr"命令。这个命令在后台执行，所以你看不到任何结果输出。但是你可以通过查看messages文件来查看运行情况:
tail -n50 /var/log/messages
正常的输出应该像这样的：
Sep 15 12:55:28 usbmgr[326]: start 0.3.5
Sep 15 12:55:28 usbmgr[328]: open error "/etc/usbmgr/preload.conf"

Sep 15 12:55:28 usbmgr[328]: USB device is matched the configuration
Sep 15 12:55:28 usbmgr[328]: "none" isn loaded

这里还有两个文件需要查看：
a) cat /proc/interrupts

2: 0 XT-PIC cascade

13: 0 XT-PIC fpu
14: 16314 XT-PIC ide0

结果：可以看到usb-uchi已经起来了，并且被分配了一个中断：这里是：int10

b) lsmod

usb-uhci 21708 0 (unused)
usbcore 49856 1 [usb-uhci]
nfsd 69928 4 (autoclean)
lockd 49340 1 (autoclean) [nfsd]
sunrpc 58244 1 (autoclean) [nfsd lockd]

结果：模块"usb-uhci"和"usbcore"应该在这里罗列。

1.5. 试一下热插拔
把带电的HP CD-Writer Plus 8210e 刻录机插到你主机的USB接口上。这样就会触动usbmgr程序来引导必须的模块。让我们
先查看一下：tail -n50 /var/log/messages。新的输出应该是报告热插拔这个事件的,所以显示像下面这样：

请先检查这行：USB device 2 (prod/vend 0x3f0/0x107)...，如果你得到的是同样的ID号(0x3f0/0x107)，那就说明你安装
的是HP8210e，如果你得到的ID是(0x3f0/0x207)，那么说明你安装的是HP8230e，它还没有被支持。
下面的12行十分重要。在"scsi: 1 host:"之后显示的是这个刻录机的有关信息。
"Detected scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0"这行告诉你你的刻录机已经被系统发现，并且设备名称是
/dev/sr0。在其他的linux版本里可能会是/dev/scd0。这两个是没有区别的。看messages文件里面显示的什么就是什么了。
可能是我的电脑太旧了，有的时候这个过程不一定成功，如果你发现信息里面没有出现供应商的名称，那你就需要重新插拔一次。两三次
后应该就没有问题了。

1.6 测试
初次的测试可以是放一张普通的光盘到刻录机里，然后mount上去:mount -r -t iso9660 /dev/sr0。
接下去就是测试刻录了：(cdrtools-1.10a04 这个包应该事先已经装好)，用cdrecord -scanbus 可以查看刻录机信息：

现在我们准备刻录了。我用的是cdrtools-1.10a04软件包。当然事先要看一下README文件。做的第一个测试是：(先放一张新的刻录盘)
mkisofs -L -l -J -r file1 file2 dir1 dir2 | cdrecord -v -pad -eject -dummy -nofix fs=4m speed=4 dev=0,0,0 -
这个命令把file1,file2,dir1,dir2做成一个iso9660格式的镜像文件，它使用了-J,-r参数，并通过管道直接传给cdrecord程序。
cdrecord程序会按照冗余模式测试写完整个光盘。但这个只是测试，并没有真正的写到刻录盘上。这个命令使用了4M的RAM作为buff，
并使用了4速刻录，使用的设备是scsi-device 0,0,0.请注意最后的那个破折号"-"，它告诉cdrecord数据是来自于管道的。请查看这个
测试刻录是不是有问题。请记住一点：一张光盘的最大容量是650M，在你刻录前请先查看要刻录的容量。

真正的刻录命令应该是：
mkisofs -L -l -J -r file1 file2 dir1 dir2 | cdrecord -v -pad -eject fs=4m speed=4 dev=0,0,0 -
你要把-dummy -nofix 这两个参数去掉。
如果你用新的CD－RW光盘就需要用下面这个命令：
mkisofs -L -l -J -r file1 file2 dir1 dir2 | cdrecord -v -pad -eject blank=fast fs=4m speed=4 dev=0,0,0 -
这个命令中的blank=fast参数将把CD-RW上的数据全部抹去，所以要当心使用。还要注意：千万不要在刻录的时候进行热插拔。
这样会造成光盘甚至你的linux系统的破坏。所以记住在拔掉前一定要先取出光盘，以防万一。
