You are talking about A-male-A-female. I often use such cables. One time
I was ready to give a class, but discoverd that I left my USB stick
(with the PP presentation) at home. Never make the same mistake again,
so I fastened my USB stick to my shoulder bag. A cable comes out of the
bag and connects to the computer, the stick does not leave the bag.

For those who think (maybe correctly) that such 'extension' cables
violate USB rules: they also exist as 'active extension' cables, with a
build-in one-socket hub.

But I was talking about A-male-A-male cables. They do exist, and the
price is (for me) almost the same as the strandard A-male-B-male. But I
have not yet seen a B-male-B-male or A-female-A-female or any other of
the more weird combinations. But Murphy dictates that they will exist
and some people will actually use them.
