uhci — UHCI USB Host Controller driver
The uhci driver provides support for UHCI-type PCI based USB controllers.
The uhci driver supports all UHCI v1.1 compliant controllers including: • Intel 82371AB/EB (PIIX4) • Intel 82371SB (PIIX3) • VIA 83C572
The following variables are available as both sysctl(8) variables and loader(8) tunables: hw.usb.uhci.debug Debug output level, where 0 is debugging disabled and larger values increase debug message verbosity. Default is 0.
The uhci device driver first appeared in FreeBSD 3.0.
The uhci driver was written by Lennart Augustsson <email@example.com> for the NetBSD project.
