USB mount point

[walking]

My kernel is 2.6.
I include the support for USB in the kernel. I mean, the support for USB in my kernel is not a module.

The /var/log/messages has the following information about usb.

kernel: usb 1-6: new high speed USB device using address 2

What does that mean? what mount point does it imply?

I tried " mount /mnt/usb" and it said mount: mount point /mnt/usb does not exist.

( in my /etc/fsaq , I added "/dev/usb1 /mnt/zip ...................."

What is the problem?

Thanks a lot!

I take it that the usb device is a storage device like a hdd or usb stick?

THen open up a terminal and do:

su -
[rootpass]
mkdir /mnt/usb
mount /dev/sda1 /mnt/usb

and now you should be able to access the usb storage device at /mnt/usb.

Thanks for your reply. However it doesn't work. Here is the message from log file.

My /etc/fstab file has " /dev/sda1 /mnt/usbflash vfat defaults,user,noauto 0 0

I typed " mount /mnt/usbflash"
It got the errors " mount: wrong fs type, bad option, bad superblock on /dev/sda1,
or too many mounted file systems"

Does my lg file say correctly about "sd_mod" has problems? What does that mount information mean?

Thanks again!

Firstly I'll check that the filesyntem of the usb drive is fat32 (or another fat fs), since you state that it is with vfat in the fstab line.

Ok if it still doesn't word run

lsmod | grep sd_mod

and tell us if anything comes up.

Another information. When I typed "

fdisk /dev/sda"

God error " Unable to open /dev/sda".


Also, I found information from /var/log/messages
Sep 16 18:02:05 scsi.agent[1485]: sd_mod: can't be loaded (for disk)
Sep 16 18:06:39 Unable to load NLS charset cp437


Where did I wrong? Thanks a lot......

I typed "lsmod | grep sd_mod" and nothing happens.

I mean, I don't have sd_mod. Is this the problem? How should I install this module?

Thanks a lot.

modprobe sd_mod

If that doesn't work, and I suspect it won't, then the module is likely missing.

If you've built your own kernel (I believe you did), then you'll need to build the scsi modules as well. Linux uses SCSI emulation for usb mass storage devices.

Thanks for reply! Yes, I built the usb-storage and SCSI in the kernel. The kernel configure file,
I enabled the CONFIG_SCSI, CONFIG_SCSI_PROC_FS, and CONFIG_BLK_DEV_SD with yes.

# SCSI device support (CONFIG_SCSI scsi_mod)
# legacy /proc/scsi support (CONFIG_SCSI_PROC_FS)
# SCSI disk support (CONFIG_BLK_DEV_SD sd_mod)
#

That means I really built sd_mod in the kernel , right? because my CONFIG_BLK_DEV_SD =yes.

I use modprobe command and got "module no found". However, that is because my sd_mod is built in the kernel instead of module, right?
