NAME
xhci - host controller driver
SYNOPSIS
usb@unit-address
DESCRIPTION
The xhci host controller driver is a USBA (Solaris USB Architecture)
compliant nexus driver that supports the eXtensible Host Controller In‐
terface Specification 1.0, an industry standard developed by Intel.
A USB 3.0 hosts include both SuperSpeed and non-SuperSpeed bus inter‐
faces, so it enables support for Low-, Full-, High- and SuperSpeed de‐
vices.
The xhci driver supports 3 of all 4 USB transfers, including interrupt,
control and bulk.

DIAGNOSTICS
All host controller errors are passed to the client drivers. Root er‐
rors are documented in hubd(4D).
In addition to being logged, the following messages can appear on the
system console. All messages are formatted in the following manner:
WARNING: <device path> <xhci><instance number>>: Error message ...
Unable to take control from BIOS. Failure is ignored.
The driver was unable to take control of the xHCI hardware from the
system's BIOS. This failure is ignored. To abort the attach on this
take-over failure, comment out a property in xhci.conf. (x86).
Unable to take control from BIOS.
The driver is unable to take control of the xHCI hardware from the
system's BIOS and aborts the attach. Contact your system vendor or
your system administrator for possible changes in BIOS settings.
You can disable a property in xhci.conf to ignore this failure.
(x86.)
Host system error detected
A serious host error is detected, either internal to the xHC or
during a host system access involving the xHC module. (In a PCI
system, conditions might include PCI Parity error, PCI Master
Abort, and PCI Target Abort.)
Host controller internal error detected
An internal error condition has been detected which requires soft‐
ware to reset and re-initialize the host controller.
Error recovery failure: Please hotplug the 2.0 hub at <device path>.
The driver failed to clear 2.0 hub's TT buffer. Remove and reinsert
the external USB2.0 hub.
