I have tested the latest release with a bunch of BT 2.1-4.0 adapters, all USB 2.0. All of them work fine.
- ASUS USB-BT211 (BT 2.1)
- ASUS USB-BT400 (BT 4.0)
- Azio BTD-V201 (BT 2.1)
- Cirago BTA-6210 (BT 2.1)
- StarTech USBBT1EDR4 (BT 4.0)
- TrendNet TBW-106UB rev.1 (BT 2.1)
- TrendNet TBW-106UB rev.2 (BT 4.0)
- Noname based on CSR chip (BT 3.0)
I suppose that most of built-in BT adapters are Class 2 devices with range up to 10m. Therefore there may be problems with loss/delaying the data from PS Moves if the host PC is relatively far from capture area.
As PS Move has magnitometer, it always gets oriented along north-south line after calibration. In contrast to Wiimote, which lacks magnitomter and takes its position during still phase of calibration as a zero rotation (as I recall, though I may be a bit wrong about exact moment).
I think that fixed orientation offset of PS Move may be caused by not ideal position of a magnitometer chip inside. There is no reasons to worry about that, because Mocap Studio does not rely on absolute orientation, but matches orientation of each controller to a scene.
