Hi, I have a Toshiba Laptop with a Bluetooth USB device integrated in it.
I can use the BT device without problems in 2.4.22, but with 2.6.0-test9=20
it doesn't work for most of the time.
USB seems to be working just fine so that shouldn't be it.
The problem is that most of the time a "hcitool inq/scan" just returns
"Inquiring ..." immediatly, without any delay like it didn't do anything.
If I remove the modules and reload them over and over again it usually=20
works after a while and when it works it stays working until I decide to=20
reboot.
I've tried to enable some debugging in hci_usb.c but I don't understand
what to make out of it.. not much that seems wrong to me..
I get one error when loading the hci_usb module though:
hub 4-0:1.0: new USB device on port 1, assigned address 2
hci_usb: probe of 4-1:1.1 failed with error -5
Don't know if it's related, the device seems fine and this showes up
even when the device happen to work.
Just let me know if there is something I can provide/test debug or=20
whatever..
This is my BT device:

Well I have now verified the same problem with the MS dongle on one of my
desktop computers (ASUS A7V333 mb), I tested with 2.6.0-test9-bk12.
Do you think it's time to try and report this to the USB people or what?
I get this type of error on both the notebook and desktop computer:
Nov 8 10:46:56 sunkan kernel: hci_usb: probe of 4-1.1:1.1 failed with error -5

> toggled and which not.
Now I've done some testing, and with hex numbers it seems to clarify a bit.
When the notebook is freshly booted I get the following values:
sw-off: 0x200
sw-on: 0x201
After I have sent a bluetooth_on:1 the values changes to:
sw-off: 0x240
sw-on: 0x241
When the switch is on and bluetooth is enabled (plugged in):
sw-on bt-on: 0x2c1
If I then move the switch back to off it goes back to 0x240
This is essentially the same numbers as earlier but in hex form, but it
seems to me that the first bit is responsible for reporting if the
switch is on or off. If I convert it to binary I get the following:
sw-off bt-off
1000000000
1001000000
sw-on bt-off
1000000001
1001000001
sw-on bt-on
1011000001
I'm not sure if I answered all your (three) questions, if not.. please
explain a bit further beacause then I didn't understand it.

don't think of highest number. You should start thinking in which bit is
set and which is not. It seems that the bluetooth_available register
will always be 15 and can be ignored at this point. The important part
is the value of wireless_switch.
It seems that we have some variables to fill in.
The hardware switch on/off
Bluetooth activated/deactivated through software
Bluetooth dongle found/disabled by USB subsystem
So you should make a table with all possible combinations and fill in
the values (in hex) for it. This is what I need to see which bit gets
toggled and which not.
Regards
Marcel

This is when I have successfully enabled bluetooth and USB has noticed
that the dongle has been plugged in.
root@swe248:/proc/acpi/toshiba# cat bluetooth
bluetooth_available: 15
wireless_switch: 705
bluetooth_on: 1
By accident I noticed that when I changed the switched from Off to On it
went up to 577 so I that is now the highest number I've seen without the
bluetooth dongle actually working.
Since I'm not used to "research" these kind of things I might not be
doing it the most efficient way, if you suggest that I shall try things
in a specific order and document it I can do it for you..

I hope that someone will notice this thread and fill in the blanks for
this.. The topic/subject is not the best though..

I played with it in all possible ways on my notebook and the highest
value I saw without bluetooth getting enabled was 576, and that was when
I tried to enable bluetooth without first flipping the switch on the
side of the notebook.
It looks like this with my changes from my last mail apllied.
This is done with the switch on the notebook in the "Off" position.
root@swe248:/proc/acpi/toshiba# cat bluetooth ; echo "bluetooth_on:1" >
bluetooth ; cat bluetooth
bluetooth_available: 15
wireless_switch: 512
bluetooth_on: 0
bluetooth_available: 15
wireless_switch: 576
bluetooth_on: 0
I'm afraid I don't have a 802.b module in my computer, it's an option
and currently I'm using BT as a cheap alternative :)
Maybe someonelse on the list have access to a Toshiba with wlan card in it?

The problem here are the information about these values. Try to play a
little bit with the switch on your notebook and get the values of the
wireless_switch and bluetooth_available registers for Bluetooth on/off
and Wirless LAN on/off.
Maybe this register could also be used to switch the Wireless LAN card
on/off and so I tend to rename the complete proc entry to wireless and
redo some parts of the patch.

here is my patch for it. I changed some stuff and left some stupid
things out. It is now switched on/off with "bluetooth:1"/"bluetooth:0"
and please check that I don't break the other stuff like fan or screen
brightness.

this should be included in the mainstream kernel source, but the code
must be a little bit cleaned up. I will check this later and send you a
patch for testing. After that I'll forward it to the maintainer.

please check this some more times and then report it to the USB mailing
list. Some of them should know what is changed in 2.6. Do you have a
desktop PC running 2.6 to verify that it is your notebook that is some
kind of buggy?

I just rebooted to check and it actually had the same problem as the
internal device. Now I'm starting to guess it maybe is USB that is the
problem, what is your opinion(s) ?

I will do some testing of this and report back if it works all the time
or if it has the same intermittend problems as my internal USB device.

Apparently many notebooks (atleast many toshiba's) have devices that can
be plugged in and out via software. The USB BT dongle in my notebook is
one of these.. There's a button on the side of the notebook that can be
used to be sure that the device is off (like in an airplane).
I found a patch for linux/driver/acpi/toshiba_acpi.c on this site:
http://nicolas.bettenburg.free.fr/linux/#c4
I hade to fiddle alot with it to make it work with 2.4.22 (I guess he
has not written it against a recent kernel). I came up with a patch that
worked ok with 2.4.22, and to my surprice it worked fine with 2.6.0 too.
My guess is that the ACPI stuff has been backported into 2.4.22 and
that's why it's almost the same.. I put the patch I use here so you can
look if you want: ftp://zappa.cx/pub/echinacea/toshiba_bluetooth.patch
It currently doesn't apply cleanly on 2.6.0-test9 but not important
stuff just comments doesn't apply.
I would be glad if this is the problem (though I think it's not since I
guess it's only job is to logically insert the USB dongle).
I'm no programmer so I might have done a poor conversion so it won't
hurt to check.

Will it help if I attach a session when it works to see if it's any
different?

Please test this. If the Microsoft is working all the time then your
problem is part of the Silicon Wave chip or some else in the internal
USB stuff of your notebook. However it works in 2.4 this must be some
kind of problem in the Linux USB subsystem which only effects this kind
of device.

The resubmit means that the previous URB fails and this is causing the
problems. But at the moment I have no idea how to track this in detail.

Right now I have CONFIG_BT_HCIUSB=y beacause I checked if that would
make things better, it did not.
SCO,Zeropacket is off

That's what I did.. I meant that the output I got from it didn't say
much to mee.. I'll attach it in the end of the mail so you can check it.

I inserted a MS Wireless Transceiver for Bluetooth and it gave the same

from the devices output I see that this device is based on a Silicon
Wave chip and it seems that I don't have this device in my list. So what
kind of model do you have and what is the output of "hciconfig -a".

What are your kernel config settings for the HCI USB driver. I prefer
you try it with these.
CONFIG_BT_HCIUSB=m
# CONFIG_BT_USB_SCO is not set
# CONFIG_BT_USB_ZERO_PACKET is not set

Include a "#define HCI_USB_DEBUG" after the last include directive.

This is a question for the USB guys. Do you have another USB Bluetooth
dongle to test with your notebook?
