[olug] problems with external USB device

[Charles Bird]

I use my ipod video(30GB one) for extra file storage on laptop and
workstation, I dont have issues until boot or shut down. So I just umount
it manually and unplug until I am ready to use.
I dont know what the deal is either, USB versions I assume.
