NOTE: This is not working totally with USB3 interfaced drives. Likely a update to the tools will fix this.

The following command:

smartctl -i /dev/sdb

Where hdparm /sdparm (and lsusb -v) show you info about the USB device this gives you the info about the device IN the USB enclosure.
Here is output:

I am going to start a new section of Linux CLI foo  that you may or may not know about. Many of these will be faster ways of doing things or getting information in a slightly different fashion. Many are old favorites of mine that I just wanted to share in case they help someone else.

Now without further ado the first command is :

ip -s l

short for ip stats list this gives a fast overview of your interfaces and  the types of packets that have been going through them. Output looks like this :

[root@pbnj lisa11]# ip -s l

More information on interface stats can be found via:
ethtool -S $DEVICE
ifconfig $device (or just ifconfig for all devices)
ifconfig -s $DEVICE

among others….
