From 4656d5de9555e263c5b4c0462b5af7e7bded1b42 Mon Sep 17 00:00:00 2001 From: David Vrabel Date: Mon, 27 Oct 2008 17:12:33 +0000 Subject: wusb: reset WUSB devices with SetAddress(0) Using a Reset Device IE to reset a WUSB device is too heavyweight as it causes the devcie to disconnect (which the USB stack does not expect and cannot handle). Instead, do a SetAddress(0); SetAddress(AuthAddr) for authenticated devices. Unauthenticated devices will not be reset and the stack will have to rely on the device timing out after TrustTimeout and disconnecting.

PALs request use of the radio with uwb_radio_start() and the radio manager will start beaconing if its not already doing so. When the last PAL has called uwb_radio_stop() beaconing will be stopped. In the future, the radio manager will have a more sophisticated channel selection algorithm, probably following the Channel Selection Policy from the WiMedia Alliance when it is finalized. For now, channel 9 (BG1, TFC1) is selected. The user may override the channel selected by the radio manager and may force the radio to stop beaconing. The WUSB Host Controller PAL makes use of this and there are two new debug PAL commands that can be used for testing.

This causes hangs when removing the whci-hcd module if a device is still connected (removing the device does an endpoint_disable which results in an ASL update to remove the qset).
