6 usba, usb - Solaris USB Architecture (USBA)
7
9 USB provides a low-cost means for attaching peripheral devices, includ‐
10 ing mass-storage devices, keyboards, mice, and printers, to a system.
11 For complete information on the USB architecture, visit the USB website
12 at http://www.usb.org.
13 USBA supports 126 hot-pluggable USB devices per USB bus. The maximum
16 data transfer rate is 1.5 Mbits (low speed USB 1.x) or 12 Mbits (full
17 speed USB 1.x) or 480 MBits (high speed USB 2.0) Mbits per second
18 (Mbps).
19 USBA adheres to the Universal Serial Bus 2.0 specification and provides
22 a transport layer abstraction to USB client drivers.
23 For information on how to write USB client drivers, see Writing Device
26 Drivers. For the latest information on writing USB drivers, visit
27 http://developers.sun.com/solaris/developer/support/driver/usb.html.
28 For a complete list of USBA interfaces, see Intro(9F) and Intro(9S).
29 Devices without a driver may have a libusb(3LIB) application. For more
32 information, see /usr/sfw/share/doc/libusb/libusb.txt.

35 Listed below are drivers and modules which either utilize or are uti‐
36 lized by USBA. Drivers in /kernel/drv are 32 bit drivers (x86 only).
37 Drivers in /kernel/drv/sparcv9 or /kernel/drv/amd64 are 64 bit drivers.

120 The messages described below may appear on the system console as well
121 as being logged. All messages are formatted in the following manner:
122 WARNING: Error message...
124 No driver found for device <device_name> (interface <number> node
128 name=<node_name>)
129 The installed Solaris software does not contain a supported driver
131 for this hardware. <number> is the interface number. <name> is
132 either the device path name or the device name.
133 Draining callbacks timed out!
136 An internal error occured. Please reboot your system. If this
138 problem persists, contact your system vendor.
139 The following messages may be logged into the system log. They are for‐
143 matted in the following manner:
144 <device path><usba<instance number>): message...
