Hardware Information: - Laptop: ASUS TUF Gaming A16 FA608UP (2025) - Bluetooth USB ID: 13d3:3612 (IMC Networks Bluetooth Radio) - Chip: Realtek RTL8852CE - WiFi works with rtw89 driver lsusb output: Bus 001 Device 002: ID 13d3:3612 IMC Networks Bluetooth Radio Chip identification from btmon: HCI version: Bluetooth 5.3 (0x0c) - Revision 12 (0x000c) LMP version: Bluetooth 5.3 (0x0c) - Subversion 34898 (0x8852) Manufacturer: Realtek Semiconductor Corporation (93) Problem: The USB ID 13d3:3612 is not in btusb's device table with BTUSB_REALTEK flag. Without this flag, btusb handles the device generically and never calls btr= tl. The chip responds to HCI commands but the radio doesn't function because firmware is never loaded. Solution: Add to drivers/bluetooth/btusb.c: { USB_DEVICE(0x13d3, 0x3612), .driver_info =3D BTUSB_REALTEK }, Tested on kernel 6.17.9-zen1-1-zen. After adding this line, btrtl loads rtl8852cu_fw_v2.bin and Bluetooth works normally. --=20 You may reply to this email to add a comment.
