usb thumbdrive. can't mount? not listed?!


Got myself a thumbdrive today and was expecting a problem or two, because I've read quite a bit about these things on these forums. I've tried the basics and read some other threads, but to no help.
I tried mounting sda through sdg, and 1-15 on each one pretty much. I have no other scsi drives on here so I would assume it'd just be sda Here's what I get.
Code:
root@floods[box]:/home/floods# mount -t vfat /dev/sda /mnt/usbstick/
mount: /dev/sda is not a valid block device
and I get the same thing when I try mounting it from the fstab.
Code:
root@floods[box]:/mnt# mount usbstick/
mount: /dev/sda is not a valid block device
root@floods[box]:/mnt#
and here is my lsmod.
Code:
root@floods[box]:/home/floods# lsmod | grep usb     
usb_storage            33920  0 
scsi_mod               78140  2 ide_scsi,usb_storage
Here's what I have in my fstab for the thumbdrive
Code:
root@floods[box]:/home/floods# cat /etc/fstab | grep sda
/dev/sda          /mnt/usbstick         vfat            user,noauto,umask=0               0   0
Here's lsusb -vvv, only the part about the lexar drive though (to save space)

        bInterval               0
Here's tail -s 3 -f /var/log/messages when I plug the drive in
Code:
Jul 31 00:36:00 floods[box] kernel: usb 3-2: USB disconnect, address 6
Jul 31 00:36:02 floods[box] kernel: usb 3-2: new full speed USB device using address 7

Jul 31 00:36:03 floods[box] usbmgr[7475]: USB device isn't matched the configuration
Now what bugs me about that part is the "bogus sysfs" portion, and the DEVPATH=/ is what I believed would be /dev/sda, but I'm not sure since I've yet to find anyone else post with that same message in /var/log/messages
It's not even directing it to /dev/sd*, which everything else I've read said it would list /dev/sd* somewhere in my /var/log/messages.

I think the usbmgr parts are from something I downloaded to try and get it working and just uninstalled, but it's still showing up. Not my problem right now though

I'm just lost on where to start!
Any pointers?
Much appreciated. especially if you even read all this and if you need any more information I'm willing to give it of course.
Thanks in advance!

normally you could watch /var/log/messages as you plug it in, you should see the name shown.

I guess your using devfs which is going to change things a bit.


Maybe try linking to something in this path

/devices/pci0000:00/0000:00:10.1/usb3/3-2/3-2:1.0/host5/5:0:0:0

I did watch /var/log/messages/ and never found *anything* relating to sd*
and I'm not using devfs.
Code:
root@floods[box]:/home/floods# cd /usr/src/linux
root@floods[box]:/usr/src/linux# cat .config | grep DEVFS
# CONFIG_DEVFS_FS is not set
should I be to get this to work? I've never tampered with devfs becuase I simply didn't know it's purpose and had no real reason to.

going to try with devfs on and see what it gives, but haven't yet. will edit this post once I do.. mainly a bump

edit: tried devfs, nothing sd* was listed in /dev then, which was what I was afraid of. I've messed with my kernel a little more (took devfs off again, other things) and now I see this in dmesg..

Try mounting it as /dev/sda1. You need to mount the partition, not the device itself. I had similar problems with my flash reader when I tried to get it working last week.

See this page too: http://www.cs.sfu.ca/%7Eggbaker/personal/cf-linux

There really needs to be a sticky thread about USB devices here.

hm, now it's getting really irritating.
I have tried mounting it as /dev/sda1, and I just read that link.

Once I got past all the kernel stuff and got sg_utils, sgcan -i gives this
Code:
root@floods[box]:/home/floods/Downloads# sg_scan -i 
/dev/sg0: scsi0 channel=0 id=0 lun=0 [em]  type=0
    LEXAR     JUMPDRIVE         1.20  [wide=0 sync=0 cmdq=0 sftre=0 pq=0x0]
which looks pretty normal.. then sg_map gives this
Code:
root@floods[box]:/home/floods/Downloads# sg_map 
/dev/sg0
it's not linked to anything?! I tried mounting /dev/sg0 but it said it's not a valid block device. ack

How about sg1

linux:/proc/scsi # ls -l /dev/sg0 /dev/sg1
crw-r----- 1 root disk 21, 0 Oct 2 2003 /dev/sg0
crw-r----- 1 root disk 21, 1 Oct 2 2003 /dev/sg1

ls-l /dev/sda /dev/sda1
brw-rw---- 1 root disk 8, 0 Oct 2 2003 /dev/sda
brw-rw---- 1 root disk 8, 1 Oct 2 2003 /dev/sda1


If the drive has more that one partition as the secure version does then you may need multilun enabled in the kernel to use the drive.


I usually run fdisk like this to see mine..


fdisk -l
Disk /dev/sdc: 255 MB, 255852544 bytes
16 heads, 32 sectors/track, 976 cylinders
Units = cylinders of 512 * 512 = 262144 bytes

Device Boot Start End Blocks Id System
/dev/sdc1 1 976 249840 83 Linux

Disk /dev/sdd: 129 MB, 129990656 bytes
16 heads, 16 sectors/track, 991 cylinders
Units = cylinders of 256 * 512 = 131072 bytes

Device Boot Start End Blocks Id System
/dev/sdd1 * 1 990 126703+ 6 FAT16

Disk /dev/hda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 1 3825 30724281 83 Linux
/dev/hda2 * 3826 7296 27880272 82 Linux swap

Code:
[root@floodsbox:/home/floods]ls -l /dev/sg0 /dev/sg1
crw-------  1 root root 21, 0 Apr 13  1999 /dev/sg0
crw-------  1 root root 21, 1 Apr 13  1999 /dev/sg1
nothing important there, right?

btw, I do have multilun enabled in my kernel, which I did *just* in case this were the problem

fdisk -l gives me no options, still. do I need to format this thing on my windows box maybe? I think I'll try that in a few.
Code:
[root@floodsbox:/home/floods]fdisk -l

Disk /dev/hda: 13.0 GB, 13020069888 bytes
255 heads, 63 sectors/track, 1582 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1         132     1060258+  82  Linux swap
/dev/hda2             133        1582    11647125    5  Extended
/dev/hda5             133        1582    11647093+  83  Linux
only portion on there I'm curious about is /dev/hda2, I know it's not the usb device but I don't know what it actually is.

This is a long shot, but worth a try:

Try some other USB mass storage device, like a USB Hard disk. Mount that using the "-t auto" option on mount. If you can access this device, then remove it and connect your thumb-drive and try accessing it just like you did for the other USB storage device.

Note: If you are using a USB hard drive - make sure you have the proper kernel modules for the particular file system.

Well, I finally had some real free time and asked a friend. he repointed me in the direction of the scsi drivers in the kernel, which I had as modules. I changed them from modules and compiled them in and it worked like a charm.
Why is it that it wouldn't work as a module?
Anyways, it works now, so I'm happy.

Thanks for all your help, it's muchly appreciated

It would work as a module. You just need to load them.

Basically the devices I posted were to show the device nodes in the event that you had to create them for some reason.

Well, even after they were loaded I couldn't get it up.

I've had quite a few issues with modules not working on my newer 2.6 kernels, but with all the 2.4 kernels I rolled they worked fine.

I've moved on to FTP and IP masquerading, so now I have newer and bigger things to learn. Just need a router, but that may be for another post another day.

Thanks for all the help David
