OK, thanks, I didn't know this. Next time... ;)

Yep. If you return the pointer (i.e. to `path') you'll get memory corruption as 
soon as you try to free (device_name).

Allright. Maybe the `path' variable should be renamed to `argument'.

Well, I prefer the idea to have the argument stored in one string and have a 
separate boolean switch that tells if the string contains a device name or a 
path. But I am always open to suggestions. ;)

Allright, this should be changed to something like this:
"Probe device information for a given path (or device, if the -d option is 
given)."

Thanks!
