There are 2 routes you can take for setting up the Raspberry Pi Zero as a USB Slave (OTG mode). 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 internet. There is no easy way to change this right now. As such, they default to USB master mode. 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. 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.īecause 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!
