[Bluez-users] Having problems with the BCM2045 USB device

[Bluez-users] Having problems with the BCM2045 USB device

[Mike Kornelson]

I have a Rocketfish RF-BTAPDT Bluetooth 2.0 EDR USB dongle. It's using 
the Broadcom BCM2045B3 chipset.

I can get it working about every 30 or so tries with a lot of fiddling. 
Here are the details:

Hardware: Dell Inspiron 9400
OS/Kernel: Ubuntu Edgy 2.6.17-10-generic

I have the bluez-utils, libbluetooth2, and kdebluetooth packages installed.

When I initially plug in the dongle my syslog spits out:

It seems like it is detecting as a keyboard and mouse. I've found this 
thread which has helped me getting it work only occasionally. 
(http://sourceforge.net/mailarchive/message.php?msg_id=37697403)

In lsmod i have these modules running:

    bcm203x                 7300  0
    bluetooth              53476  4 hci_usb,bnep,rfcomm,l2cap
    hci_usb                18068  0
    ...list truncated...

I've tried loading hci_usb with the reset=1 parameter. I've also tried 
the hid2hci utility but it always says: "No devices in HCI mode found" 
(which is odd because shouldn't that say No devices in HID mode found 
because i'm running it as "sudo hid2hci --tohci"?)

lsusb outputs:

If i remember correctly (from when the dongle did work) there was a 
fourth Broadcom device.

The Broadcom devices in /proc/bus/usb/devices are: (i cut out the other 
devices, let me know if you need more detail)

    T:  Bus=03 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 57 Spd=12  MxCh= 3

    E:  Ad=81(I) Atr=03(Int.) MxPS=   4 Ivl=10msl

And running hciconfig display nothing until it actually detects. Then it 
will show the hci0 device. So until it is detected and working running 
any of the "hciconfig hci0 up" or "hciconfig hci0 reset" just gives a 
"Can't get device info: No such device".

In the thread i mentioned above Marcel posts:

That seems to be my problem. Can anyone shed any more light on what the 
init sequence might be?

Any help on this problem would be much appreciated.
