NAME

       usba, usb - Solaris USB Architecture (USBA)

DESCRIPTION

       USB provides a low-cost means for attaching peripheral devices, including mass-storage devices, keyboards, mice, and printers, to a system.
       For complete information on the USB architecture, visit the USB website at http://www.usb.org.

       USBA supports 126 hot-pluggable USB devices per USB bus. The maximum data transfer rate is 1.5 Mbits (low speed USB 1.x) or 12 Mbits  (full
       speed USB 1.x) or 480 MBits (high speed USB 2.0) Mbits per second (Mbps).

       USBA adheres to the Universal Serial Bus 2.0 specification and provides a transport layer abstraction to USB client drivers.

       For  information  on  how to write USB client drivers, see Writing Device Drivers. For the latest information on writing USB drivers, visit
       http://developers.sun.com/solaris/developer/support/driver/usb.html. For a complete list of USBA interfaces, see Intro(9F) and Intro(9S).

       Devices without a driver may have a  libusb(3LIB) application. For more information, see /usr/sfw/share/doc/libusb/libusb.txt.

FILES

       Listed below are drivers and modules which either utilize or are utilized by USBA. Drivers in /kernel/drv are 32 bit  drivers  (x86  only).
       Drivers in /kernel/drv/sparcv9 or /kernel/drv/amd64 are 64 bit drivers.
