これは結城浩さんの運用されていた YukiWiki に当時 Coffee 様 (青い鴉（ぶるくろ）さん）がかかれていた文章です。 ただ 2018 年 3 月 7 日に YukiWiki が運用停止したため消えてしまいました。その記事のバックアップです。
今は 404 ですが、もともとの記事の URL は http://www.hyuki.com/yukiwiki/wiki.cgi?%A5%C7%A5%B9%A5%DE%A1%BC%A5%C1%A4%AC%B5%AF%A4%AD%A4%EB%CD%FD%CD%B3 になります。
昔、自分がとても感銘を受けた文章なので、このまま読めなくなるのはとてももったいないと思い、バックアップとして公開しています。

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).
The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

These instruction are for Windows, on my Linux installation(Fedora 21) everything works by just installing serialport with npm (I don't know why!).
These are the steps I did to build node serialport for electron (formerly atom-shell) for Windows. I am completely certain there is a better way to do it, but since I struggled with it for quite a while, here is a solution anyway.
You need some version of Visual studio installed, I have VS 2012 Express for Desktop.
