What device out there can plug into a eSATA/USB combo port?

What device out there can plug into a eSATA/USB combo port?

http://en.wikipedia.org/wiki/ESATA/USB
eSATA/USB ports can be used for either eSATAp(Power over eSATA), eSATA
or USB devices. ... eSATA/USB ports are run at a maximum of 3.0 Gbit/s
and are backwards compatible with devices at eSATA 3.0 Gbit/s (eSATA 2)
and also at 1.5Gbit/s (eSATA 1). The USB port runs at a maximum of
480Mbit/s (USB 2.0) and is backwards compatible with USB 480 Mbit/s (USB
2.0) and USB 12Mbit/s (1.0).

What device out there can plug into a eSATA/USB combo port?

Well, *something* plugs in there.

I had a hell of a time, finding a simple article with pinout information.
Such information is needed, to figure out compatibility tables, like
"what can my laptop power" or "what can my desktop power".

"There are two versions of EUHPs - the 5V EUHP and the 12V EUHP. All the
EUHPs on the Notebook are of the 5V types and it can power most of the
5V type of devices such as external 2.5" hard drives, SSD and slim optical
drives.

On Desktop system or motherboard, the EUHP is most likely the 12V type
which carries both 5V and 12V power over the cable. Both type of EUHPs
use the same EUHP connector. On the 5V type of EUHP, there are no
P12 and P13 pins inside the port (see diagram above)."

I'm not at all certain about the following. I have a feeling this might
be the cable end, rather than the computer end. The pinout seems
reversed, yet the picture of this thing looks like a port on the
back of a computer.

+--- 7 pin ESATA section --+ (As viewed from ???)
/ \
GND GND B+ B- GND A- A+ GND VBUS = +12V ???
P13 P11 P10 P9 P8 P7 P6 P5 P12 missing on laptop
(missing no 3.5" ESATA on laptop
on P1 P2 P3 P4
laptop) VBUS D- D+ GND
+5V
powers
USB or 2.5" ESATA
potentially

\ /
+- 4 pin USB section -+

I'd view it as three groups of pins.

A standard 7 pin SATA section
A standard 4 pin USB section (giving access to +5V, laptop or desktop)
A two pin +12V/GND supply (giving access to +12V, desktop only, for 3.5" drives)

What's missing from the rosy description on the Addonics page, is what
happens when your small SSD drive with SATA connector, needs 3.3V to operate.
A 5V to 3.3V conversion step will be required (and might run too hot to hide
within a cable housing).

Now, you can start shopping. You would start, by finding references in Wikipedia
to announced products, then the same product web page should have more
of them.

(When the file named something like " TS1qxR5g.pdf.part " downloads,
rename it to some_stupid_manual.pdf so you can open it. It seems the
first characters of the downloaded file name are random, so no two people
get the same file name. Very, very clever. )

That 2.5" enclosure, happens to have an EUHP connector on it, so you'd
need an EUHP to EUHP cord. And that one, the required cable comes
with the unit. To buy the cable separately, costs about $17.

This cable, is for going from ESATAP to a raw hard drive. If you use
a 2.5" raw hard drive, this cable will always work. If you plug
in a 3.5" raw hard drive, it's a function of the desktop plug as
to whether it will work. Some reviewer comments are, that it
didn't work, and that is because their desktop was missing
the two pins providing 12V and ground return (P12 and P13).
So for 3.5" drives, it's a bit "hit and miss", and depends on
whether your desktop manufacturer provided P12 and P13, and
connected them up.

I sure hope they decide on a standard name for that connector. I've
been inconsistent in naming it above. But that's the job
of the idiots of sata-io.org to decide. And as usual, they made
a mess of it. Just like their inability to see that people
might like abbreviations to refer to 150MB/sec, 300MB/sec, or
600MB/sec SATA interfaces (which I've taken to calling SATA I,
SATA II, SATA III, when I'm not supposed to). Neither ESATAP
nor EUHP, really does justice to the capabilities.

You're right. It takes a great effort to figure out how to use this
thing and what's out there that works with it. I wonder if it'll ever
take off.

Way too complicated in my opinion. The port might break easily?
