NAME
usba, usb - Solaris USB Architecture (USBA)
DESCRIPTION
USB provides a low-cost means for attaching peripheral dev-
ices, 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 writ-
ing 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) applica-
tion. 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.

NOTES
Booting from USB mass-storage devices is not supported on
SPARC, but is supported on X86.
