I'm confused. According to the USB On The Go FAQ at:
http://www.usb.org/faq/ans6

Q2: Do both portable devices have to be dual-role in order for both
devices on order to connect and operate?
A2: No, dual-role devices will connect to all PCs, and will also have
host functionality to connect to supported USB peripherals.

From that I gathered that only the host side of a USB-OTG connection
needs a special chip. Am I wrong?
