Having Amlogic Android TV Android 5.1 without Bluetooth inbuilt, but having root access. I'm trying to install an external USB Bluetooth driver btusb.ko which is compatible with Android 5.1 and has the same kernel version as my TV.

When trying to insmod btusb.ko, I get following dmesg | grep btusb

<4>[ 2303.391438@3] btusb: Unknown symbol kmem_cache_alloc_trace (err 0)
<4>[ 2303.391569@3] btusb: Unknown symbol _mcount (err 0)
  • You need the source code of the Linux kernel that is used in your device. Then you can cross-compile the module which will be compatible with your kernel.
