Hello, Adam
Very sorry for confusing you with ASUS USB-BT400 model. I played with it and iPi Recorder several months ago, and as I've recalled when seeing your message, I got it working. But that is untrue actually, as I have tested now. I've just managed to install MiJ drivers for it, but never got it recognized in DS3 tool or successfully paired with PS Move (after writing dongle's MAC address to PS Move).
However, I have just tested TRENDnet TBW-106UB model, and it's working OK with 2 PS Moves (not considering
the problem you've posted earlier).
Is this dongle recognized by the OS at all? I'm asking because I had problem with mine - when it's inserted to the very bottom of USB slot, the contact seems very poor and it is not visible to the system. I need to pull it out a bit to make it work.
Once visible in Device Manager, the dongle shows up in DS3 tool (
USB\VID_0A12&PID_0001), and I can install MiJ driver for it and pair PS Moves to it. Then turn PS Moves on and run iPi Recorder, and they are on list.
You can also check VID and PID numbers of BT dongle in Device Manager (right-click on device, tab 'Details', select 'Device Instance Path' in combobox). So we are sure that you have exactly the same TRENDnet device as mine.
Regarding HID error with Kensington one, I may suppose that that dongle is designed to work with only one BT device at once. That's why it is causing errors when trying to connect the second PS Move.
