I thought: "The <linux/usb_gadget.h> API makes it easy for peripherals and other devices embedding GNU/Linux system software to act in the USB "device" (slave) role." http://www.linux-usb.org/gadget/ Doesn't that mean that gadget API can be used by USB device manufacturers who want an Open Source solution for the device's USB functionality? To be more clear, isn't that API used on the device itself, and not for a Linux loadable module to be used by my workstation machine with that device plugged in to the USB port? -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
