I have a solid light on the Cisco tuning adapter but when plugged it into the usb port the Tivo doesn't see the tuning adapter and indicates that it is missing. Yet if I press the power button on the adapter, turning it off, the Tivo sees the adapter and indicates that it is connected. The issue is that I can no longer receive the SDV channels since the Tivo doesn't see the adapter when it is on and it doesn't get the SDV channel map when the the adapter is powered down. Any suggestions? This is a new issue as the tunning adapter previously communicated with the Tivo as it is supposed to do.
