Trouble mounting usb flash drive - help!

Installing and Using OpenWrt

Hi,

I'm having trouble working out what is wrong.
I have installed kmod-usb-storage, and block mount but the actual mount command fails with

dmesg shows:

4155.864398] scsi 0:0:0:0: Direct-Access     USB      Flash Disk       1100 PQ: 0 ANSI: 0 CCS

[ 4155.910707]  sda: sda1
[ 4155.918669] sd 0:0:0:0: [sda] Attached SCSI removable disk

fdisk -l gives

Device     Boot Start     End Sectors   Size Id Type
/dev/sda1  *      512 1957887 1957376 955.8M  6 FAT16

do I need another kmod driver for msdos or vfat?

Thanks very much

Sorry, missed mount output

root@OpenWrt:/etc# mount /dev/sda1 /mnt/sda1
mount: mounting /dev/sda1 on /mnt/sda1 failed: Invalid argument
root@OpenWrt:/etc# ls /mnt
sda1

Did you create the mount target? mkdir/mnt/sda1

You may need to install the kmods for the file system you are trying to mount.

I think that kmod-fs-vfat handles FAT16 and FAT32 formats. kmod-usb-storage only attaches the drive into a raw /dev/sd block device, but an additional driver is needed to understand the filesystem.

Hi,
Thanks to every one.

I manged to get this to work by including in the image:
kmod-fs-vfat, kmod-fs-msdos, kmod-block2mtd, kmod-usb-core, kmod-usb-storage, and when the device has the new image 'opkg install block-mount'!
