Description of problem:
Samsung Mighty Drive 500MB usb stick cannot be mounted after plugging in because
device /dev/sda1 does not exist.  On investigation, the required modules are not being loaded during boot.  This is fixed after boot by either running System Tools --> Hardware Browser, or manually loading scsi_mod, sd_mod and usb-storage.

More permanent workaround is to edit /etc/rc.sysinit to load the required modules during boot.  Usb stick connected during boot can then be automounted and icon will be present on desktop as expected.

Suggests something wrong in /etc/rc.sysinit?

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Add usual line to /etc/fstab to allow mounting of usb stick
2. Plug in usb stick
3. Try to mount
  

Actual Results:  Mount fails.  /dev/sda1 does not exist.

Expected Results:  vfat filesystem on /dev/sda1 should get mounted on mountpoint.
