SYNOPSIS

cdcef* at usbf?
DESCRIPTION
OpenBSD provides machine-independent bus support and drivers for Universal Serial Bus (USB) functions, making it possible in principle for machines running OpenBSD to act as USB device to a USB host.
The OpenBSD usbf
driver has three layers: the controller, the logical device, and the
function layer. The controller attaches to a physical bus. The logical
device attaches to the controller and the function attaches to the logical
device.
Function drivers implement the characteristics of a particular USB device class that the USB host will see when the device is connected to the bus.
SUPPORTED FUNCTIONS
OpenBSD includes the following machine-independent USB function drivers, sorted by device type and driver name:
Communication devices
- cdcef(4)
- Communication Device Class Ethernet Emulation Model USB network adapter.
