54 test software, like the "usbtest" driver, to put your hardware
57 Gadget Zero also works with the host-side "usb-skeleton" driver,
58 and with many kinds of host-side test software. You may need
59 to tweak product and vendor IDs before host software knows about
60 this device, and arrange to select an appropriate configuration.

69 You can configure this device to enumerate using the device
70 identifiers of the USB-OTG test device. That means that when
71 this gadget connects to another OTG device, with this one using
72 the "B-Peripheral" role, that device will use HNP to let this
73 one serve as the USB host instead (in the "B-Host" role).
85 This Gadget Audio driver is compatible with USB Audio Class
87 1 AudioStreaming Interface each for USB-OUT and USB-IN.
90 This driver doesn't expect any real Audio codec to be present
91 on the device - the audio streams are simply sinked to and
92 sourced from a virtual ALSA sound card created. The user-space
93 application may choose to do whatever it wants with the data
94 received from the USB Host and choose to provide whatever it
95 wants as audio data to the USB Host.
