There are a bunch of little boards like these. This one has USB-B socket that faces your computers and TTL Serial that faces your project. When you plug your project into a computer the computer sees it as a serial port. https://www.sparkfun.com/products/718
If all you need is the USB-B connector then you can get free samples here http://www.molex.com/molex/products/datasheet.jsp?part=active/0548190519_IO_CONNECTORS.xml&channel=Products&Lang=en-US If you don't like "free" the above place, Sparkfun" will sell them for $1.50 On Thu, Jul 25, 2013 at 2:45 PM, Bob Stewart <b...@evoria.net> wrote: > Do you have a good solution for USB?
