regarding USB

Hi

I configured the OSK5912 for supporting USB FLASH
according to the follwing procedure

USb Flash has been detected.
But when i am trying to mount USB(step 3) it is
showing this error

mount: Mounting /dev/sda1 on /mnt/usb failed: No such device or address

Kindly help me in this regard

Using USB Flash memory with the OSK5912

1. Compile the kernel with following options
enabled.

Device Drivers --->
USB support --->
<*> Support for host-side USB ( CONFIG_USB )
<*> OHCI HCD support ( CONFIG_USB_OHCI_HCD )
<*> USB Mass Storage Support ( CONFIG_USB_STORAGE )

SCSI device support ---> ( CONFIG_SCSI )
<*> SCSI disk support ( CONFIG_BLK_DEV_SD )

At least one file system must be enabled. The
below describes vfat file system as an example (compatible with Windows).

"File systems" --->
"DOS/FAT/NT Filesystems" ---> ( CONFIG_FAT_FS)
<*> MSDOS fs support ( CONFIG_MSDOS_FS )
<*> VFAT ( Windows-95 fs support) ( CONFIG_VFAT_FS )

"File systems" --->
"Partition Types" --->
[*] Advanced partition selection (
CONFIG_PARTITION_ADVANCED )
[*] PC BIOS (MSDOS partition table) (
CONFIG_MSDOS_PARTITION )

"File systems" --->
"Native Language Support" ---> ( CONFIG_NLS )
<*> Code Page 437 (United States...) (
CONFIG_NLS_CODEPAGE_437 )
<*> NLS ISO8859 (Latan 1...) ( CONFIG_NLS_ISO8859_1
)

2. Register the usb

Add the following line in OSK's '/etc/fstab'
file.

/dev/sda1 /mnt/usb vfat defaults 0 0

3. Mount the file system

# mkdir /mnt/usb
# mknod /dev/sda1 b 8 1
# mount /dev/sda1 /mnt/usb -t vfat

4. Access the USB Flash.

Now, you can access the USB Flash contents under
/mnt/usb directory.

# ls /mnt/usb

5. Remove the USB Flash

Ensure umount before removing the device.

# umount /mnt/usb

No need to do this. In menuconfig you should choose the Host Controller (not sure if it is OHCI or Inventra - one of them) After you plug in the mass storage driver you should see the following kind of logs:

sd 0:0:0:0: [sda] Assuming drive cache: write through
sda:<7>usb-storage: queuecommand called

sd 0:0:0:0: [sda] Attached SCSI removable disk

Once you see the SCASI logs (that is important: sda1), you can issue the command:
mkdir mnt
mount -t vfat /dev/sda1 mnt

mnt directory will have to mass storage contents.

Hi

after connecting USBto OSK5912 i am geeting messge like this

Instead of SDA1 i am geeting SDB1
so i created a node for sdb1
and i mounted usb using sdb1 node
still i am getting error
