Several very popular USB WebCams with USB Audio support are causing
loginwindow to crash when the are plugged in or unplugged. The crash
happens in a call to CFStringCompare in
HALComponentHelper::DeviceIsNowAvailable(), which is part of a
XIOAudioDeviceManager::NotificationThread. This is logged in RADAR as
#2973082.
I'm wondering if anyone can tell me what string the HALComponentHelper
is trying to use? I'm wondering if I can stop using the
AppleUSBAudio.kext, and replace it with my own kext which sets whatever
string is missing, to make this crash go away.
Thanks for any help you can provide,
