Whoever wonders which Bluetooth hardware works with BlueZ (Bluetooth stack for Linux) will come across the following statement from the Bluetooth SIG on the compatibility list:
Whether or not you're selling them makes no difference. The problem is due to the distribution of them from your Web site. Please note that the use and distribution of non-qualified products is a violation of the Bluetooth License Agreement. As neither of these products have been qualified using Linux it is illegal to make them available for public use.
Due to this idiotic attitude, it is no longer possible to refer to the compatibility of Bluetooth products with Linux on holtmann.org. Can it get any more stupid?
