This host controller driver emulates USB, looping all data transfer
requests back to a USB "gadget driver" in the same host. The host
- side is the master; the gadget side is the slave. Gadget drivers
+ side is the controller; the gadget side is the device. Gadget drivers
can be high, full, or low speed; and they have access to endpoints
like those from NET2280, PXA2xx, or SA1100 hardware.
