-/*
- * Filesystem based user-mode API to USB Gadget controller hardware
- *
- * Other than ep0 operations, most things are done by read() and write()
- * on endpoint files found in one directory. They are configured by
- * writing descriptors, and then may be used for normal stream style
- * i/o requests. When ep0 is configured, the device can enumerate;
- * when it's closed, the device disconnects from usb. Operations on
- * ep0 require ioctl() operations.
- *
- * Configuration and device descriptors get written to /dev/gadget/$CHIP,
- * which may then be used to read usb_gadgetfs_event structs. The driver
- * may activate endpoints as it handles SET_CONFIGURATION setup events,
- * or earlier; writing endpoint descriptors to /dev/gadget/$ENDPOINT
- * then performing data transfers by reading or writing.
