.SH NAME
usba, usb \- Solaris USB Architecture (USBA)
.SH DESCRIPTION
.LP
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.
.sp
.LP
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).
.sp
.LP
USBA adheres to the \fIUniversal Serial Bus 2.0\fR specification and provides a
transport layer abstraction to USB client drivers.
.sp
.LP
For information on how to write USB client drivers, see \fIWriting Device
Drivers\fR. For the latest information on writing USB drivers, visit
\fIhttp://developers.sun.com/solaris/developer/support/driver/usb.html\fR. For
a complete list of USBA interfaces, see \fBIntro\fR(9F) and \fBIntro\fR(9S).
.sp
.LP
Devices without a driver may have a \fBlibusb\fR(3LIB) application. For more
information, see \fB/usr/sfw/share/doc/libusb/libusb.txt\fR.
.SH FILES
.LP
Listed below are drivers and modules which either utilize or are utilized by
USBA. Drivers in \fB/kernel/drv\fR are 32 bit drivers (x86 only). Drivers in
\fB/kernel/drv/sparcv9\fR or \fB/kernel/drv/amd64\fR are 64 bit drivers.
