It looks like the Logitech link uses a key down/key up method. Sometimes the key up doesn't make it accross the RF link. However, after a timeout, the key up is sent again. Unfortunately, this sends 11 repeats in that time. This is enough to cause the PS3 to go into repeat mode. This only effects keys that repeat such as the arrow keys. When I tried to create a workaround in our firmware, I determined that the Logitech link had several issues. So I couldn't create a clean and robust way to cover up the bad behavior. Depending on the installation environement, this problem could occur even within 10ft or so, which I found surprising. Perhaps their RF link does not coexist well with Bluetooth. I can't imagine Logitech would market something that only works at 10 feet or so.
