54 __FBSDID("$FreeBSD$");
57 * Driver for Atheros AR5523 USB parts.
59 * The driver requires firmware to be loaded into the device. This
60 * is done on device discovery from a user application (uathload)
61 * that is launched by devd when a device with suitable product ID
62 * is recognized. Once firmware has been loaded the device will
63 * reset the USB port and re-attach with the original product ID+1
64 * and this driver will be attached. The firmware is licensed for
65 * general use (royalty free) and may be incorporated in products.
66 * Note that the firmware normally packaged with the NDIS drivers
67 * for these devices does not work in this way and so does not work
