Devices usba(7D) 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.
