I would like to use V-USB for a project I am working on. The microcontroller I want to use as a USB device is running off of battery power. What should I do with Vbus from USB? Can I leave it unconnected? Do I need to to anything so that my device is detected?
General discussions about V-USB, our firmware-only implementation of a low speed USB device on Atmel's AVR microcontrollers
