Description of problem:
When I plug in the USB Mass Storage device to the USB port, no new device is
created in the /dev directory.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Plug in the USB Mass Storage device to the USB port.
Actual Results: "tail -f /var/log/messages" output:
kernel: hub.c: USB new device connect on bus1/2, assigned device number 5
/etc/hotplug/usb.agent: Setup usb-storage for USB product 8ec/802/100
modprobe: modprobe: Can't locate module block-major-2
Expected Results: The USB Mass Storage device should be able to use.
Devices in /dev are not created by hotplug. They are permanently
present as part of the "dev" package.

This is what comes out from the /var/log/messages file. Any solution?
I do not see a problem. What happens if you run "fdisk /dev/sda"?
I am able to mount the usb storage with 'mount /dev/sda /mnt/usbstorage'
command, but I am only able to mount as ext2 file system. I tried to format the
file system as vfat with this command ' mkfs -t vfat /dev/sda ' but the command
failed to perform the action. Please advice.
This is the output of runing fdisk
# fdisk /dev/sda
Command (m for help): p
Disk /dev/sda: 2 heads, 32 sectors, 250 cylinders
Units = cylinders of 64 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 250 7984 e Win95 FAT16 (LBA)
Command (m for help):
Format in Windows or in Camera/Appliance, then use /dev/sda1,
mount -t msdos /dev/sda1 /mnt/usbstorage
May I close this now?
