[Bluez-users] hciconfig problems

[Mariusz Dziuba]

Hello,

I'm using Redhat with kernel 2.4.20-18.9. I use an Acer USB Bluetooth Dongle (ID 0b7a:07d0). I habe installed the latest bluez-libs followed by bluez-utils with no problem.

In my /etc/modules.conf i added:
alias net-pf-31 bluez
alias bt-proto-0 l2cap
alias bt-proto-2 sco
alias bt-proto-3 rfcomm
alias bt-proto-4 bnep
alias bt-proto-5 cmtp
alias tty-ldisc-15 hci_uart

After a restart of my linux i load the hci_usb:
>modprobe hci_usb

Start of the Host Controller:
>hcid

hciconfig returns:
hci0:   Type: USB
        BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
        DOWN RUNNING
        RX bytes:0 acl:0 sco:0 events:0 errors:0
        TX bytes:0 acl:0 sco:0 commands:0 errors:0

lsmod returns:
Module                  Size  Used by    Tainted: PF
hci_usb                 9752   1
bluez                  40260   9  [hci_usb]
...
..
.

When i try to start hci0, then hciconfig hangsup or i get an "Speicherzugriffsfehler" (segmentation fault):
>hciconfig hci0 up

In the Processlist i see:
 4221 pts/1    D      0:00 hciconfig hci0 up

And hciconfig still returns:
hci0:   Type: USB
        BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
        DOWN RUNNING
        RX bytes:0 acl:0 sco:0 events:0 errors:0
        TX bytes:0 acl:0 sco:0 commands:0 errors:0


can some one help me with this problem. I'm really desperate.

Thanx.
Marius

is this a AMD64 system running a 64-bit operating system? If yes, then
you should update your kernel and the library/utilities to the latest
version.

Marcel
