Something tells me that issues exist between the CI-V circuit differences with the 7000 and the levels seen or expected to be seen by the Lenovo laptop USB ports.
Efforts continue but maybe not for long!! :-)

After all the noise, it’s just your Lenovo that is FUBAR.
Check it with other USB devices.
Neighbor has the problem, every time he turns his stuff on, with one computer, the USB ports move.
