USB Storage woes on Mandrake 10.0

dedgsus · 06-19-2004, 11:19 PM

I just installed Mandrake 10.0 on my laptop (my first linux install) and am trying to set up my external usb hard drive... I haven't been able to find the device to mount the drive. I've tried to mount /dev/sda but that wasn't working so I started a little digging.

When I turn on the hard drive I find the following information in /proc/bus/usb/devices:

T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 4 Spd=12 MxCh= 0
D: Ver= 1.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=04ce ProdID=0002 Rev= 0.22
S: Manufacturer=ScanLogic USBIDE
S: Product=ScanLogic USBIDE
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=05 Prot=00 Driver=(none)
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms

And dmesg shows:

usb 1-2: new full speed USB device using address 2

I'm a little concerned by the "Driver=(none)"... On all the posts I've found on the matter, I usually see some sort of scsi emulation start, but I don't get that... do I need to specifically enable it or could it not be in the kernel? How can I do/check this? Any other suggestions?

Thanks!

The scsi and usb modules are loaded from /etc/modprobe.conf. The relevant lines for me are:

install scsi_hostadapter /sbin/modprobe usb-storage; /bin/true
install usb-interface /sbin/modprobe usb-uhci; /sbin/modprobe ehci-hcd; /bin/true

If you have those lines, the scsi modules should load. You can confirm that they are loaded by running as root:

# lsmod

which lists all loaded modules.

One way to see if the drive is being detected is to run as root:

# fdisk -l /dev/sda

that will list all partitions on /dev/sda which fdisk recognizes even if the partitions are not mounted.

In my /etc/modprobe.conf I have:

install scsi_hostadapter /sbin/modprobe usb-storage; /bin/true
install usb-interface /sbin/modprobe usb-uhci; /bin/true

lsmod shows:

usb-storage 72932 0
scsi_mod 114648 4 sd_mod,sg,sr_mod,usb-storage
uhci-hcd 29104 0
usbcore 99132 5 hid,usb-storage,uhci-hcd

So I see that scsi_mod is running and that usb-storage is set up, so that is good but now any suggestions why scsi emulation doesn't start when the device is plugged in? Because it doesn't start, the drive doesn't show up with "fdisk -l" Could my problem be that modprobe.conf doesn't have the "/sbin/modprobe ehci-hcd" entry?

That's probably not it. Ehci is for usb 2.0; the drive should still work at usb 1.x speeds which uses the uhci module. Do you have any other usb storage devices connected? After connecting the drive, is there a /dev/sda file?

I have an external usb hard drive(Maxtor One Touch) which works fine in mdk10 and worked with a little tweaking in mdk9.2. If you want to compare, here's my entire lsmod output:
