Can't use capi/cmtp with bfusb

Hi,

i try to get my BlueFritz! USB-Stick get working on my Kurobox (An NAS based on an PPC-CPU) but i've the problem, that i can't use the capi device after loading all modules (See messages at the end of this mail).

Here some infos what I do:

1. I plug the stick on the Kurobox and the kernel does recognize the stick:

usb 2-1: new full speed USB device using ohci_hcd and address 2 usb 2-1: configuration #1 chosen from 1 choice
Bluetooth: Core ver 2.10
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: HCI USB driver ver 2.9
usbcore: registered new driver hci_usb

Loaded modules are now:

hci_usb                19260  0
bluetooth              66476  1 hci_usb

2. Next I load the bfusb driver with _modprobe bfusb_

Syslog output:
Bluetooth: BlueFRITZ! USB driver ver 1.1
usbcore: registered new driver bfusb

Modules loaded now:

bfusb                  14244  0
firmware_class         12224  1 bfusb
hci_usb                19260  0
bluetooth              66476  2 bfusb,hci_usb

3. Now i execute /etc/init.d/bluez-utils start

Output:
Starting bluez-utils: hcid sdpd rfcomm.

Syslog output:
Bluetooth: L2CAP ver 2.8
Bluetooth: L2CAP socket layer initialized
Bluetooth: RFCOMM socket layer initialized
Bluetooth: RFCOMM TTY layer initialized
Bluetooth: RFCOMM ver 1.8

Loaded modules:

rfcomm                 48572  0
l2cap                  27140  5 rfcomm
bfusb                  14244  0
firmware_class         12224  1 bfusb
hci_usb                19260  2
bluetooth              66476  8 rfcomm,l2cap,bfusb,hci_usb

4. When i enter hciconfig, i see the bluez interface - it's up:

hci0: Type: USB

    BD Address: 00:04:0E:89:DA:BA ACL MTU: 120:20 SCO MTU: 0:0
    UP RUNNING PSCAN ISCAN
    RX bytes:101 acl:0 sco:0 events:13 errors:0
    TX bytes:300 acl:0 sco:0 commands:13 errors:0

Additionally i execute hciconfig hci0 lp because holtmann writes in his how-to (http://www.holtmann.org/linux/bluetooth/isdn.html), that this could be necessary:

hci0: Type: USB
BD Address: 00:04:0E:89:DA:BA ACL MTU: 120:20 SCO MTU: 0:0 Link policy: RSWITCH HOLD SNIFF PARK

5. I execute now _modprobe cmtp_

Syslog output:
CAPI Subsystem Rev 1.1.2.8
Bluetooth: CMTP (CAPI Emulation) ver 1.0

Loaded modules:

cmtp                   24320  0
kernelcapi             50548  1 cmtp
rfcomm                 48572  0
l2cap                  27140  6 cmtp,rfcomm
bfusb                  14244  0
firmware_class         12224  1 bfusb
hci_usb                19260  2
bluetooth              66476  9 cmtp,rfcomm,l2cap,bfusb,hci_usb

7. Next I do an _modprobe capi_ because.

Syslog output:
capifs: Rev 1.1.2.3
capi20: Rev 1.1.2.7: started up with major 68 (middleware+capifs)

Modules:

Module                  Size  Used by

kernelcapi             50548  2 capi,cmtp
rfcomm                 48572  0
l2cap                  27140  6 cmtp,rfcomm
bfusb                  14244  0
firmware_class         12224  1 bfusb
hci_usb                19260  2
bluetooth              66476  9 cmtp,rfcomm,l2cap,bfusb,hci_usb

8. Yet I do an ciptool search:

Searching ...

    Checking service for 00:04:0E:85:C2:21
    Connecting to device 00:04:0E:85:C2:21

Syslog output:
Bluetooth: Found 1 CAPI controller(s) on device 00:04:0E:85:C2:21
kcapi: Controller 1: 00:04:0E:85:C2:21 attached
kcapi: card 1 "00:04:0E:85:C2:21" ready.

Now .... when i enter now an capiinfo, i should get an full info about available capi features, right?

I get this here:

Number of Controllers : 1
Controller 1:
Manufacturer: AVM Berlin
CAPI Version: 2.0
Manufacturer Version: 3.101-04 (49.20)

FAC REQ - Illegal command or subcommand or message length less than 12 bytes (0x1102)

Other capi applications doesn't also work so i think, the connection isn't established right. What I do wrong?

Here some further details:
Linux lansrv01 2.6.17.8-mh5_kurobox_hg #2 Sat Aug 19 01:49:26 CEST 2006 ppc GNU/Linux
- Kernel includes patch from http://www.bluez.org/patches.html

I hope i give enough details so someone can help me, solving this problem.

Kind regards
Manuel Bernhardt

Hi,

really no one where have an idea? If other information are needed, say it and you get it. It would be very nice if i would get bfusb working with cmtp on my nas because i could use my nas as an voice box for ex. I hope, i'dnt overrun the mailinglist with the detailed description in my first mail.

Hi Manuel,

I think the problem is that your CPU is big endian and the CAPI subsystem is not working on big endian systems. I tried to fix it at one point, but never succeeded.

Marcel

Hi Marcel,

thank you for this information. That means, that i should annoy the ISDN4Linux-Mailinglist (or which project/group is the right contact point in your opinion?) with my concern? If you say, you need only an System for testing and it's no big job, do this big endian changes, I also could give you temporary access to my ppc-box for developing. I'm not an c/c++ expert, but if i can contribute to open source by giving access to hardware, I do it.

I search now a long time for a way, get CAPI on one of my NAS and now i thought, i found a way because the bluefritz usb stick doesn't need hardware depended firmware (i tried first an "old" fritz!x but avm rejected my request for an ppc firmware) but now the kernel code doesn't match the requirements... "nice"

Manuel

Hi Manuel,

go ahead and annoy the ISDN4Linux mailing list. And it is not a problem of hardware. I have an Ultra 10 from Sun and a Apple Quad G5 here. The CAPI subsystem is the problem. It is hardcoded for little endian in a strange way. At least it works with AMD64 and EM64T now.

Regards

Marcel

Ok! But thanks for the fact, that's an CAPI problem. That helps me a lot annoy the right people :-)

And: Thx for made BlueFritz and features available to linux !

Have a nice day
Manuel
