Hello, I can not get the Bluetooth dongle to work on the mqmaker WiTi Board  device
The drivers installed, the system determines that Bluetooth has been connected, but hciconfig output the following:

hci0: Type: BR/EDR Bus: USB
BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
DOWN
RX bytes:0 acl:0 sco:0 events:0 errors:0
TX bytes:0 acl:0 sco:0 commands:1 errors:

hciconfig hci0 up output:
Can't init device hci0: Operation timed out (145)

I'm using OpenWrt 4.4.14.

What could be the problem?
