I was playing with the idea of having my usb disk have a static name to it
(like simply mobile). I was able to get everything I needed except for one
thing. The serial number. I can look in /sys to find the model, vendor,
and firmware. I tried scsi_id from udev which doesn't work. scsiinfo from
scsitools shows it as having a blank serial number. I tried reading scsi
page 0x80 and 0x83 but it's not supported.
Kernel 2.6.10 vanilla.

I realize I probably could grab "serial" from the above, however, I was
thinking of the usb-ide dongle which you have 1 usb device that you can
attach to various hardware thus the serial # of the usb device won't be of
much good.
Ideas?
