+ * The HWA driver is a simple layer that forwards requests to the WAHC
+ * (Wire Adater Host Controller) or WUSBHC (Wireless USB Host
+ * Controller) layers.
+ *
+ * Host Wire Adapter is the 'WUSB 1.0 standard' name for Wireless-USB
+ * Host Controller that is connected to your system via USB (a USB
+ * dongle that implements a USB host...). There is also a Device Wired
+ * Adaptor, DWA (Wireless USB hub) that uses the same mechanism for
+ * transferring data (it is after all a USB host connected via
+ * Wireless USB), we have a common layer called Wire Adapter Host
+ * Controller that does all the hard work. The WUSBHC (Wireless USB
+ * Host Controller) is the part common to WUSB Host Controllers, the
+ * HWA and the PCI-based one, that is implemented following the WHCI
+ * spec. All these layers are implemented in ../wusbcore.
+ *
+ * The main functions are hwahc_op_urb_{en,de}queue(), that pass the
+ * job of converting a URB to a Wire Adapter
+ *
+ * Entry points:
+ *
+ *   hwahc_driver_*()   Driver initialization, registration and
+ *                      teardown.
+ *
+ *   hwahc_probe()	New device came up, create an instance for
+ *                      it [from device enumeration].
+ *
+ *   hwahc_disconnect()	Remove device instance [from device
+ *                      enumeration].
+ *
+ *   [__]hwahc_op_*()   Host-Wire-Adaptor specific functions for
+ *                      starting/stopping/etc (some might be made also
+ *                      DWA).
