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.
