I cross-checked the device names, subversions and kernel behavior in devices/bluetooth/btbcm.c (Linux v5.6, | |
commit dde8010be0a0). The last two columns represent the firmware names the kernel will look for in USB or UART HCI | |
modes. @ denotes that the device is explicitly listed in kernel, . when the generic naming is used. | |
