Hi,

I have Lenovo laptop with an Intel wireless and Bluetooth adapter, running CentOS 6.9. The wireless works just fine, but I can’t seem to get Bluetooth to work. When I try to force it up from the command line I get

# hciconfig hci0 up Can’t init device hci0: Invalid request code (56)

There is also a similar message message in /var/log/messages from start-up on boot. The device info from “hciconfig” also seems a bit suspicious to me – notice how the address has all 0s:

# hciconfig -a 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:48 acl:0 sco:0 events:8 errors:0
    TX bytes:24 acl:0 sco:0 commands:12 errors:4

/var/log/messages indicates that firmware is loaded correctly

# egrep “iwlwifi.*firmware” /var/log/messages Nov 20 09:24:16 osl-97214 kernel: iwlwifi 0000:04:00.0: firmware:
requesting iwlwifi-8000C-17.ucode Nov 20 09:24:16 osl-97214 kernel: iwlwifi 0000:04:00.0: firmware:

and I think the following shows that the device is actually there

# lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 046d:c52b Logitech, Inc.

The bluetooth kernel modules should be loaded, too (but perhaps I need some extra driver or whatever?)

# lsmod  | grep bluetooth bluetooth              97799  6 sco,bnep,l2cap,btusb rfkill                 19255  5 cfg80211,bluetooth,thinkpad_acpi

Does anyone have any idea what’s wrong here? Is there any way at all I
can enable Bluetooth on this system?

Thanks,
