1- He holds no USB port. 2- We can finally turn on / off the PS3 since its remote control. 3- To ensure proper operation macros I spot next to the TV: it works fine 2m PS3. 4- The controls are extremely fast: no latency due to bridge Infrared Bluetooth. 5- The repeatability (eg when one leaves his finger pressed down to actually show) is properly managed. 6- PowerOFF macro works even if one uses the PlayTV.
This unit has its own transformer.
NOTE: The Harmony PS3 adapter does not use IRs codes PS2 remote. It has its own code set. So no conflict if you have a PS2. By cons, it only works with Harmony remotes.
NOTE 2: You can not save 2 on the PS3 Bluetooth remote controls: it's either the optional remote control Sony or Logitech adapter.
