Linux (Ubuntu, Debian, Arch): Kernel 5.4+ includes native support via the btusb kernel module. However, firmware is required. Most distros automatically load /lib/firmware/rtl_bt/rtl8761b_fw.bin and /lib/firmware/rtl_bt/rtl8761b_config.bin. If missing, the adapter will enumerate but fail to scan.
macOS/Hackintosh: No official driver. The RTL8761B is not supported by Apple’s Broadcom-only Bluetooth stack. Some community projects (like OpenIntelWireless) have attempted reverse engineering, but the BTA-403 is effectively useless on macOS.
Android (via USB OTG): Android’s Linux kernel can support it, but only on rooted devices with custom firmware loading. Not practical.
