 Posted: Fri Sep 12, 2003 10:17 pm Post subject: Can't mount USB CF reader - sd_mod nonexistant? |
 |
|
After reading through this post, and creating /dev/sda1, I still can't get my USB CF reader to work. I found no option in the kernel configuration for enabling sd_mod. I grepped "find /" and "lsmod" for "sd_mod", but found nothing. /etc/kernel/settings has, in its first line:
| Code: | | STORAGE_MODULES="sd_mod sg sr_mod \ |
I assume it at least attempts to use sd_mod, but I can't figure out why it's not running. So I grepped dmesg:
| Code: | # dmesg | grep scsi -i
SCSI subsystem driver Revision: 1.00
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
scsi: <fdomain> Detection failed (no card)
Failed initialization of WD-7000 SCSI card! |
And I also tried to just go ahead and mount the SCSI device I created with mknod:
| Code: | # mount -t vfat /dev/sda1 /mnt/flash/
mount: /dev/sda1 is not a valid block device |
I've tried "rmmod usb-storage", putting in a CF card, and "modprobe usb-storage", tried enabling more things in the kernel and recompiling (I use genkernel since I've never been lucky rolling my own by hand, though I have used genkernel --config to change things around). Nothing works.
I am at a loss here. What should I be doing in order to get my system to recognize my CF card? It appears as though SCSI is available in the kernel, but for some reason doesn't run. Does anyone have a suggestion to help a guy out? :-/ |

sd_mod is SCSI Disk support, so you need to make a module for it. It's just above SCSI CDROM support (sr_mod) and SCSI generic (sg). You will need those two for a CD burner, but not for the CF reader. If you do not have an actual SCSI adapter make sure that there are no low-Level drivers selected in that section.
To automate the detection of the reader, emerge hotplug and set it to start at boot:
| Code: |
rc-update add hotplug default
|
Start it now. If the reader is plugged in with a card inserted, usb-storage and sd_mod should load automagically:
| Code: |
/etc/init.d/hotplug start
|
Check with 'ls -l /dev/discs/' to see if one of them points to your new scsi device. Hopefully you'll see something like this:
| Code: |
disc2 -> ../scsi/host0/bus0/target0/lun0
|
In my fstab I like to force ownership by my regular user on vfat partitions:
| Code: |
/dev/sda1 /mnt/cf vfat rw,noauto,users,uid=1000,gid=100 0 0
|
Then it mounts simply with 'mount /mnt/cf'. |

Thanks for the reply. I was with you all the way up until "mount /mnt/{mountpoint}". I got
| Code: | # ls -l /dev/discs/
total 0
lr-xr-xr-x 1 root root 30 Dec 31 1969 disc0 -> ../ide/host0/bus0/target0/lun0
lr-xr-xr-x 1 root root 30 Dec 31 1969 disc1 -> ../ide/host0/bus0/target1/lun0 |
In "lun0" are two devices:
| Code: | root@wallaby lun0 # pwd
/dev/ide/host0/bus0/target1/lun0
root@wallaby lun0 # file *
disc: block special (3/64)
part1: block special (3/65) |
I tried mounting "disc" to /mnt/flash', but it gave me the "wrong fs type, bad option, etc." error. Mounting "part1" worked, but it mounted to my hdb1.
My /etc/fstab contains, among other lines:
| Code: | | /dev/sda1 /mnt/flash vfat rw,noauto,users,uid=1000,gid=100 0 0 |
Hotplug has already been set to auto-start at boot, and it was already started. Mounting with "mount /mnt/flash" gave me:
| Code: | # mount /mnt/flash/
mount: /dev/sda1 is not a valid block device |
I created /dev/sda1 using:
| Code: | | mknod /dev/sda1 b 8 1 |
I don't know if I should have created it some other way, but that's what I used. No luck. Yet. :-/ |

/dev/discs/ should show all your hard drives, including the pseudo ones like a cf card or thumb drive. These will show up as SCSI drives, so something is still wrong somewhere in your setup. It looks like you have two IDE drives.
Don't 'mknod' the device. Let devfs take care of that, it will be a symlink to the partition. I'd get rid of the one that you made.
You might want to unplug the reader, unload the modules (I like 'modprobe -r'), restart hotplug, and then plug the reader back in with a CF card already in it. If you run 'tail -f /var/log/syslog' while you do this you can see what's happening.
That's all I can think of at the moment. |

Hey guys, I wanted to post here because I'm having a bit of aproblem with what seems to be mount being happy with what I'm mounting.
I got all the modules compiled in, and when I insert the CF card, the /dev/sda1 device is created (however it requires me to rmmod usb-storage and then modprobe it back in... any suggestions on how to "supermount" this media?)
Anyway, here's the details below:
Gentoo Sources r7
Transcend USB 2.0 CF Reader
usbview/KDE Info Util both show it by name
fstab entry
| Code: | | /dev/sda1 /mnt/flash vfat user,noauto,ro 0 0 |

or too many mounted file systems
