Bring in USB4BSD, Hans Petter Selasky rework of the USB stack that includes significant features and SMP safety. This commit includes a more or less complete rewrite of the *BSD USB stack, including Host Controller and Device Controller drivers and updating all existing USB drivers to use the new USB API: 1) A brief feature list: - A new and mutex enabled USB API. - Many USB drivers are now running Giant free. - Linux USB kernel compatibility layer. - New UGEN backend and libusb library, finally solves the "driver unloading" problem. The new BSD licensed libusb20 library is fully compatible with libusb-0.1.12 from sourceforge. - New "usbconfig" utility, for easy configuration of USB. - Full support for Split transactions, which means you can use your full speed USB audio device on a high speed USB HUB. - Full support for HS ISOC transactions, which makes writing drivers for various HS webcams possible, for example. - Full support for USB on embedded platforms, mostly cache flushing and buffer invalidating stuff. - Safer parsing of USB descriptors. - Autodetect of annoying USB install disks. - Support for USB device side mode, also called USB gadget mode, using the same API like the USB host side. In other words the new USB stack is symmetric with regard to host and device side. - Support for USB transfers like I/O vectors, means more throughput and less interrupts. - ... see the FreeBSD quarterly status reports under "USB project" 2) To enable the driver in the default kernel build: 2.a) Remove all existing USB device options from your kernel config file. 2.b) Add the following USB device options to your kernel configuration file: # USB core support device usb2_core # USB controller support device usb2_controller device usb2_controller_ehci device usb2_controller_ohci device usb2_controller_uhci # USB mass storage support device usb2_storage device usb2_storage_mass # USB ethernet support, requires miibus device usb2_ethernet device usb2_ethernet_aue device usb2_ethernet_axe device usb2_ethernet_cdce device usb2_ethernet_cue device usb2_ethernet_kue device usb2_ethernet_rue device usb2_ethernet_dav # USB wireless LAN support device usb2_wlan device usb2_wlan_rum device usb2_wlan_ral device usb2_wlan_zyd # USB serial device support device usb2_serial device usb2_serial_ark device usb2_serial_bsa device usb2_serial_bser device usb2_serial_chcom device usb2_serial_cycom device usb2_serial_foma device usb2_serial_ftdi device usb2_serial_gensa device usb2_serial_ipaq device usb2_serial_lpt device usb2_serial_mct device usb2_serial_modem device usb2_serial_moscom device usb2_serial_plcom device usb2_serial_visor device usb2_serial_vscom # USB bluetooth support device usb2_bluetooth device usb2_bluetooth_ng # USB input device support device usb2_input device usb2_input_hid device usb2_input_kbd device usb2_input_ms # USB sound and MIDI device support device usb2_sound 2) To enable the driver at runtime: 2.a) Unload all existing USB modules. If USB is compiled into the kernel then you might have to build a new kernel. 2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same base name like the kernel device option.
