kernel 2.6.0,使用USB硬盘,真的搞不定!!
我用的是RH9,升级到kernel 2.6.0后,usbcore,ohci-hcd,ehci-hcd,uhci-hcd模块统统正常加载,usb-storage,hotplug也直接built-in了,当我几次插拔USB硬盘的时候,/var/log/messages中出现如下信息:Dec 26 11:24:23 localhost kernel: hub 4-0:1.0: new USB device on port 1, assigned address 15
Dec 26 11:25:09 localhost kernel: hub 4-0:1.0: port 1 disabled by hub (EMI?), re-enabling...<6>usb 4-1: USB disconnect, address 15

Dec 26 11:25:42 localhost kernel: hub 4-0:1.0: new USB device on port 1, assigned address 19
在几个尝试之后,显然最后是成功了,可是运行mount /dev/sda /mnt/dos, sda1,sdb什么都试过了,就是不行. 实际上/proc/partitions里面根本就没有显示有新的分区.
2.6内核是不是把USB硬盘换位置了?哪位高手知道?Anyone succeeded in mounting aUSB hard disk? SCSI支持选了没有？
U盘在linux下要虚拟成SCSI硬盘来访问，需要的支持有：
USB支持(usb-core)，USB存储设备支持(usb-storage)，USB－UHCI支持（好像是这个名字）
SCSI基本支持（sg），SCSI硬盘支持（scd-mod，忘记是否这个名字了），scsi模拟支持（这个在ATA设备里选，不在SCSI里）
内核里的hotplug反而不是必要（反正我没有选）
你都编译了没有？ SCSI支持选了没有？

All of them are in.

When insert the USB HD in, dmesg shows:
hub 4-0:1.0: new USB device on port 1, assigned address 5
That means a success, I guess. But the corresponding lines in /proc/bus/usb/devices shows:
T:Bus=04 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=5 Spd=12MxCh= 0

E:Ad=02(O) Atr=02(Bulk) MxPS=64 Ivl=0ms
What does "Driver=(none)" mean? No driver for it?
Whew, my USB HD gonna be a pile of shit on Linux? :-( Sorry, I missed the module usb-storage.
But still it doesn't wanna get to work, when isert the USB HD in, dmesg shows:
hub 4-0:1.0: new USB device on port 1, assigned address 8
scsi3 : SCSI emulation for USB Mass Storage devices
scsi scan: 37 byte inquiry failed with code 458752.Consider BLIST_INQUIRY_36 for this device

Ah,it seems that some coding work should be done. Who's gonna tell me how to fix it? 好像漏了一个scsi硬盘支持了，模块名字好像是scd-mod，要虚拟成scsi硬盘才能工作，因此scsi硬盘支持也得选 好像漏了一个scsi硬盘支持了，模块名字好像是scd-mod，要虚拟成scsi硬盘才能工作，因此scsi硬盘支持也得选
scsi-mod or scd-mod?
scd looks like for scsi cdrom :-) sd_mod i think llc
想死我了！ sd_mod i think

still it doesn't work! dmesg shows:

What's wrong? so depressing :-( I digged into the device attributes, in /proc/bus/usb/devices it syas, this USB HD's Vendor ID is 5e3, Product ID is 702, Rev(Release version?) is 1.13, device protocol is 00, interface protocol is 50. but in modules.usbmap, there' no module support for this type of device, although there's a similar one, but the interface protocol is 00.
maybe the usb-storage the kernel 2.6 includes can't drive my USB HD? need a special driver?
:-( :-( :-( llc

有这事？不会吧？我经常来这里啊，发贴也不少 呵呵，一句话，很快就元旦了，新年到了，同乐同乐！（再灌就成水贴了，希望龙版莫怪莫怪 :mrgreen: ） :-D
happy new year!
