What is this USB storage?

Whenever I use the 'Safely Remove Hardware' tool, say to remove USB
stick F:, I also see this mystery entry, with no drive letter.
https://dl.dropboxusercontent.com/u/.../WhatUSB-1.jpg

How can I discover what it is please? And why does it have no drive
letter?

It could be you printer attached via USB port. Try to disconnect the
printer and then see if it is still visible as in your image. I had
this issue when I was using XP in those days.

If so, this program may show it as a "USB Composite" device.
That's for when a complex device has multiple sub-devices
internal to it.

I don't know if the program will crawl a whole tree or not,
or it's more for looking at the port level. But it's worth
a try, just to see what is there.

Is it a laptop?
Does that machine have a card reader or cd/dvd drive?

NSA drives do not have drive letters. It would tend to make them
accessible.

To remove an NSA drive, you need
http://www.centralsecurity.gov/NSA/U...emovalTool.exe but
without a security clearance, you won't be able to download.

Maybe you have a friend with a security clearance ID code.

Thanks for that.

Such a difference between the two sites! The Microsoft one actually
looked as if it might be useful, but I got lost in a maze of webpages
just looking for the .exe, and eventually gave up. The Nirsoft one, in
contrast, has a link to it on the page. (OK, zipped and near the bottom,

Yes, and there explanation pages are just as hard to understand.

IIUC, they won't hire anyone who got a C or above in English Composition
in college or high school. Grades D or below are acceptable..

They have standards and they strive to meet them.

Thanks to all for those helpful suggestions.

I've installed both USB Tree Viewer and Nirsoft's USBDeview, but find
both dauntingly complicated. It's astonishing how much information
there is to report about a USB device like a memory stick plugged into
a socket on the front of a PC case!

Here's an example from USBDeview. (I've split the very wide display
into five sections.)

https://dl.dropboxusercontent.com/u/...-Mystery-1.jpg

I'm quite out of my depth with this stuff. But I suspect the issue I
reported was somehow due to my using several USB sticks, sometimes in
two different USB sockets, sometimes both at once, sometimes after
renaming them which XP Explorer allows. The background for anyone
curious is that I was testing the transfer of music tracks and
playlists from my PC to my car's player, using the auto sync feature
in my music management program MediaMonkey.

A large part of my confusion is because I've never grasped how Windows
deals with names and drive letters of USB devices and HDs, internal or
external. Plus the apparent absence of any helpful information about
the physical current location of a particular device. What I want is a
list with entries like this:

'32 GB USB memory stick currently plugged into fixed USB socket on
front of PC.'

or

'32 GB USB memory stick currently plugged into socket #4 of USB Power
Hub brand xyz'

That's a device with SD card slot or similar. Card
reads come with as many as 52 to 1 or as low as 1 to 1
(single SD slot, only takes SD). I have a thing like
a USB flash stick, with an SD hole on it, and all
it handles is SD (from my camera).

A card reader can be present on a printer.

A card reader can be present on a computer, in
the place where the floppy drive used to be.

Third party card readers also exist for
5.25" bays, and you can add some pretty fancy
ones there. As well as perhaps a couple USB
ports for other things.

The drive letters for card readers, tend to stay
in place, even if the media is absent. More lore

Thanks Paul, appreciate that helpful advice.

I wonder if my built-in card reader could be implicated?
https://dl.dropboxusercontent.com/u/...e-SDreader.JPG

It's rarely used (and certainly not during any of my recent USB
testing). But I do recall that years ago (the PC is 7 years old) it
would sometimes be erratic, occasionally not recognising the inserted
SD card.

At a guess, that should use up four drive letters,
even when no media is in each slot.

You could disconnect it, but it might be tied into a
hub chip that your USB key (in picture) is using. It
really depends on how it is wired.

The USB cabling may have a 2x5 on the end, with one
pin missing which functions as a keying feature. Each USB
port uses a 1x4 section of that connector. One half of the
cable, could be the 1x4 that feeds the Genesis. The second
1x4 worth of pins, could operate the USB port in the picture.
So no hub chip is needed in that case. But if one USB port
internally is being used to run all that hardware, then
there's probably a hub in there somewhere.

Apple makes this a bit easier in their OS, because
they have a page which shows a stick drawing of the
USB connectivity. If hub devices are present, you
can see the Y they create in the USB map, and that
helps tell you how all the stuff is connected.

Not many OSes, will map physical location to some
information the OS has to share. While there was
some SATA RAID softwares that would do that (display
a picture showing the SATA port that needed attention),
generally that's not a feature on PCs. We have to "guess"
at it instead.
