We have users using Speechmikes on Windows XP pro sp2. The speechmike seems to work when it is unplugged from the laptop and replugged into the same or different USB port. It continues to work, until the user reboots. It doesn’t make a difference about the length of time of reboot. We already tried deactivating the power saver on the usb port option, but it didn’t seem to help. Please get back to me with a solution ASAP. Thank You.
