17 The \fBuhci\fR host controller driver is a \fBUSBA \fR (Solaris USB
18 Architecture) compliant nexus driver that supports the \fIUniversal Host
19 Controller Interface Specification 1.1\fR, an industry standard developed by
20 Intel. The \fBuhci\fR driver supports all USB transfers, including interrupt,
21 control, isochronous and bulk.
