Can't get USB Bluetooth working with 10.11 El Capitan

[RehabMan]

So, I've tried to reboot with no success. Moreover, the device is not detected by the system (it is not in the list of USB devices). I've seen this once earlier and thought that I moved the tape away from PIN 51 when installing the card. I looked at the card, but the tape was still there. I added more tape, to make sure, that there is no way for the card to contact to PIN51 and after booting my Mac the device was back. Thus I'm pretty sure that pin is well covered by the tape, so it seems to me even more strange, that it may disappear without any reason.

UPD1: I've disconnected and connected back the combo card and booted my Mac. List of USB devices show me my device, however it is still not working.

UPD2: I've figured out that resetting SMC helps to bring the BT device BCM20702A0 back to list of USB devices. However it doesn't make it work. By the way BTFirmwareUpdate fix doesn't work either with the same error as earlier.

Doesn't sound like you read my previous post. No mention of removing Android File Transfer.

I did, and I removed Android File Transfer Agent, which was the reason of the issue, as per FAQ. However I didn't completely remove Android File Transfer. It doesn't seem that it will help, but to remove the whole thing.

I deleted Android File Transfer, but it didn't help me. Moreover, device disappeared from USB devices list again.

Check in ioreg to see if the device is there... Not possible to make it work if the bluetooth controller is not active on the USB bus.

No, it is not there. I've got no clue, what could be the reason of this behavior. After each attempt to get an access to Bluetooth it disappears from the list until I reset SMC.
