Serial Number

[David Henderson]

Gang,

     I'm trying to use mdev to create some unique device file names and 
would like to use the obvious choice of a serial number, however, that 
information doesn't appear in any of the env output from mdev.  Does 
anyone know of a way to obtain this information via mdev?  I've also 
looked at hdparm, but it doesn't appear to work with USB drives and I 
need a universal solution.  Any help would greatly be appreciated.

Thanks,
Dave
