Hi, just learning, but doesn't strncmp() of the 5th subdirectory solve 
whether its ata or
usb, using example2 DEVPATH. My system looks like I could list 
/sys/block, parse for "sd"
then for ata or usb. If you go by /sys/devices, I believe you can get 
fw, hwmon, net, audio.
Even with example2, you screen out "sd" vs "sr".
Don't shout me, just trying to understand.
