bthps3 is associated with the Bluetooth HID Profile (HPS) support – specifically related to HID over GATT (HoG) or older profile handling. It may appear in logs or application outputs when a Bluetooth profile or service tries to initialize but fails to find the underlying radio hardware.

If you’ve encountered the error message “bthps3: Bluetooth host radio not found” while trying to use Bluetooth on a Linux system, you’re not alone. This error typically appears when a Bluetooth service or utility (like bluetoothd or a profile client) attempts to interact with the Bluetooth adapter but cannot detect any available host radio (i.e., a local Bluetooth controller).
Some motherboards and laptops have a hardware-level toggle for Bluetooth and Wi-Fi inside the BIOS. If disabled there, Windows cannot see the radio at all.
