DESCRIPTION
The hwahc driver is a USBA (Solaris USB Architecture) compliant nexus
driver that supports the Wireless USB 1.0 Host Wire Adapter Host Con‐
troller, 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.
