Public bug reported:
Hello,
Using brand-new, clean, Ubuntu 9.04 final:
I have a problem with my external USB disk on reboot. Well, actually, on
boot. It's an USB disk with external power supply. If the USB disk is
powered on at boot, it will show up in 'lsusb'-output, but no device
will be created in '/dev/ '.
Once I power down and then restore power on the USB disk, an entry in
'/dev/ ' is created and the USB disk is automatically mounted. This
shows up in /var/log/messages:

Which made me think it had something to do with the USB Mass Storage
support module. This turned out to be true, so, when I boot with my USB
disk powered on, it isn't recognized. When I do a manual 'modprobe
usb_storage', an entry in '/dev/ ' is created and the USB disk is
mounted.
For now I have added 'usb_storage' to '/etc/modules' but it would be
nice if this step wasn't necessary in the future!
