- Host Wire Adapter Host Controller Driver

Description

The hwahc driver is a USBA (Solaris USB Architecture) compliant nexus driver that supports the Wireless USB 1.0 Host Wire Adapter Host Controller, an industry standard developed by USB-IF.

A Host Wire Adapter (HWA) is a USB device whose upstream connection is a USB 2.0 wired interface. The HWA operates as a host to a cluster of downstream Wireless USB devices.

The hwahc driver supports bulk, interrupt and control transfers.
