Hello mailing list,

my bluetooth usb-stick worked fine with kernel up to 3.19. With 4.x
there is no hci device found.

lsusb
Bus 004 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth
Dongle (HCI mode)

hcitool dev
Devices:

sudo hciconfig
hci0:	Type: BR/EDR  Bus: USB
	BD Address: 00:15:83:15:A3:0B  ACL MTU: 672:4  SCO MTU: 48:1
	DOWN
	RX bytes:890 acl:0 sco:0 events:30 errors:0
	TX bytes:126 acl:0 sco:0 commands:30 errors:0

sudo hciconfig hci0 up
Can't init device hci0: Operation not supported (95)

rfkill list
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN

Is this a regression. Or does it work in different way with 4.x?

Regards,

Norbert
