HCITool bluetooth device not showing.

[3cvil]

Followed all of the correct dependancy installations, and have tried to use hcitool. My computer has a working bluetooth chip. It is enabled. I am running Kali Linux on VIrtualBox. When hcitool dev is ran, it shows no devices and as such, the program emits this error:
raceback (most recent call last):
File "/home/AppleJuice/app.py", line 148, in
main()
File "/home/AppleJuice/app.py", line 117, in main
toggle_device(dev_id, True)
File "/home/AppleJuice/utils/bluetooth_utils.py", line 97, in toggle_device
fcntl.ioctl(hci_sock.fileno(),
OSError: [Errno 38] Function not implemented

However, Kali Linux does recognise the device. I have enabled, disabled bluetooth, checked it, and rfkill recognises the device as unblocked hard and soft, with: the correct device id needed (hci0):

ID TYPE DEVICE SOFT HARD
0 bluetooth hci0 unblocked unblocked

Meaning that Kali Linux does know the bluetooth device exists.. When I run the bluetooth manager/adapter programs in Kali, cpu usage spikes but no gui shows up, meaning an issue with Kali? Tried to fix but no avail.. Any help?
