Got it working! Using these:
Trendnet USB Ethernet: https://www.amazon.com/gp/product/B00FFJ0RKE/
GZZ USB C Hub: https://www.amazon.com/gp/product/B07GQ9GR41/
Tivo will not accept USB C Power Delivery from the Hub so I still have to use Micro USB. But the Flirc works great. I think my problem before was that I was using some random AUX IR Codes in my remotes database. I did not realize the Flirc is only compatible with certain IR. So, once I switched to something more standard, Panasonic TV Codes in my case, everything worked great!
