There probably wasn't until very recently, because USB was supposed to
be limited to about 10 feet. However there are now USB cables with
built-in amplifers. They come in lengths up to, iirc 100 feet, and
shorter ones can be used in series. Maybe the longer ones can too.
Some have a bulge in the middle, like a snake who ate a rat, and they
woudl be very hard to snake. Others have the bulge close to the end,
but plainly, you can't use two in series if the sheet rock is already
in, and even if you put the cables in first, I suppose sometime an amp
will probably break. I guess that means buy one long enough in the
first place, use no staples, maybe put something in around corners to
make pulling out a bad one and replacing it with a new one easier.
Amazingly, where cables are cheap, even these are not very expensive.
I want find out what is clogging my gutters, on my two-story house, and
I thought it woudl be fun, rather than borrow a ladder, so I bought iirc
a 25 foot and a 15 foot. But I had trouble tying the camera to the
extension pole, and then it got cold out. If winter ever ends, I'm
going to try again. In device manager, I disabled the built-in
camera, since I couldnt' find another way to make a usb camera work, but
I also bought another cable to go in the basement window to the desktop

I agree, that AFAIK there isn't any such thing either. The way it was
worded led to the question. The poster didn't say USB charging sockets.
He said wired USB sockets.
Regarding the USB charging ones, they seem kind of cool at first and
they aren't necessarily a bad idea. But IDK how useful they really are.
I guess if you came across one somewhere, needed a charge, and had your
cable, you could use it. But all you need besides the cable is the charger
and they have gotten very small. So, I'm not sure they are all that cool.
And IDK what the cost delta is versus a regular receptacle, the long term
reliability of those typically cheap power supplies, etc.
They run $20 to $40 depending on configuration. You say, "all you need
is the charger" but it is not that simple for some people. They carry
multiple devices these days.
I can see having one or two in the house. A family of four can easily
have a half dozen things on charge at night. Phone, MP3 player, GPS,
hair trimmer, shaver, whatever.
I'm not about to change out a recepticle, but in a remodel or new
construction I would.

I put in a USB charger/power receptacle and so far so good.
It reduced the clutter by eliminating a couple of wall wart chargers
and freeing up the receptacles.
MCM does sell wall plates for USB data cables and you can get
extenders that will take the signal 100' or more.

Thank you all. The USB will be used for power (recharging) only and we've
decided to wire the kitchen counter with one. Looks like this wasn't a buil
d time decision and that USBs can be installed at any time by just buying a
new wall unit. I wonder if they'll be a problem with GFI requirements in
the kitchen? Thanks again.
USB is fast becoming a power as well as a data standard. The power capacity
was recently increased to 100 watts -- up from 10 watts or less a few years
ago. USB is the most popular plug standard in the world with more than10
billion in use. I'm hearing about LED table lamps being designed with an
LED plug for charging other electronic devices and have seen a couple of
examples in newer hotels. But why not just use USB cords, plugs and outlets
for table and floor lamps? LEDs are low-voltage DC devices and so the LED
driver would be simpler and less expensive.
That ignores all the overhead (physical and $$$) to turn simple
120/240 volt ac into USB level DC. Do you really want to have to put
a USB "wall wart" inside every plug in your house? Keeping in mind
that it takes 1500 watts just to run a toaster... you will never be
running your toaster off a USB wall outlet. And when that USB wall
wart inside the outlet which is inside the wall burns out are you
prepared to pay an electrician $75 to replace it when now all you need
to do it buy a new $5 wall wart if the old one burns out? Low voltage
DC is terrible for "electric distribution" but within a house you
could have one big (and expensive) Garage Wall Wart by the breaker
panel and run DC wires IN ADDITION TO your 120VAC to all the outlets.
But to set up something capable of 100 watts at EACH outlet is going
to be VERY expensive. It's adding a ton of needless expense to avoid
using a $5 wall wart in those few places you need one. Personally, I
don't see it as a viable strategy for general household use. Building
them into the base of Lamps is a nice idea though.
What I would suggest if we are going to talk about revising how we
"wire our houses" is that the form factor for wall outlets be changed
to a form that is twice as wide and each outlet rotated 90 degrees so
that it can easily accommodate plugs and wall warts at the same time,
perhaps even set up with three female outlets instead of today's two.
In the never ending cycle to keep us confused and continue to get our
money, I am sure that in 5 years from now, or less, they will change the
shape and size of the USB plugs so we have to buy all new stuff once
Standard 120V AC outlets have been the same for decades. I'll stick with
them. Some of the dollar stores sell USB adaptors that plug into a
common 120V AC outlet, and they cost as little as $1 each. I dont see
any reason to have built in USB plugs in my walls when they will likely
be obsolete in a few years anyhow.
It's just like the cellphones. Some years ago, each brand had a
different charger plug. It appeared in the last few years they had
standardized so all phones had what they call the "mini-USB". All of a
sudden it seems that some smartphones need larger plugs on their
chargers. Im not sure why, but once again we as consumers have to spend
more money to satisfy changes once again. It never ends!
And just for fun, I'd like to see a USB outlet that can power a Kitchen
Electric Range *(240V at 50A), or my Welder *(240V at 60A). Or how about
a 50HP 3 phase electric motor......
Last but not least, just how many USB devices do you really have? I am
not a hi-tech person, but the only USB powered device I own, is my
cellphone. So, why would I need USB outlets? My cellphone has both a
120V AC adaptor for in the house, and a 12V DC adaptor for my car.
Everything else I own that uses a USB plug, MUST be plugged into my
computer, because it's part of the computer, and the USB cord sends data
as well as power.

Mini-USB hs been replaced with "micro-USB". Micro-USB is a about 60% as
thick as mini-USB (much less than the thousandth the name suggests). For
both types, there are cables that connect to a noumal USB outlet.

Not five years from now, it's starting to come out right now: USB-C.
It's a single connector standard that all (future, new) devices will
be able to use. The cable has USB-C connectors at both ends, the
connectors are much smaller than the standard USB plug, the cable is
reversible, and if the devices support the new USB power delivery
specification, it can be used to charge devices up to four times
faster, trade charges with other devices, and transfer data between
devices - all with a single small cable. No more power cable plus data
cable, no more power bricks. Just one small cable to
power/charge/transfer power/transfer data between devices.
Both Apple and Google have announced their new hardware will be
featuring it, so it's already entering the mainstream.
