No such device using hcitool scan

[desword]

When I connect the Nordic 51822 DK to the PC, I can not detect the device using

root@riot-VirtualBox:/home/riot# hcitool scan
Device is not available: No such device

When i type the jlink to detect, there show two devcies:

J-Link>ShowEmuList
J-Link[0]: Connection: USB, Serial number: 123456, ProductName: J-Link
J-Link[1]: Connection: USB, Serial number: 123456, ProductName: J-Link

what's wrong?

@Wojtek Thanks, however, I still can not detect the BLE device, as shown in devzone.nordicsemi.com/.../
