0a12:0001 Cambridge Silicon Radio Bluetooth Dongle not working

Linux Tolnedra 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux

Ubuntu 2.6.31-14.48-generic

Hi Maarten,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 460743

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

The bug is still valid, and as you can see it is also valid at my (new) 32bit laptop. So it is apparently not a 64 bit specific issue :-S

There is a workaround: adding "usbcore.autosuspend=0" to Kernel command line.
But that solution unacceptable for portable machines and should be treated in Linux.

Tried the workaround listed above "usbcore.autosuspend=0", and am afraid it didn't work for me. Symptoms are the same, "Connection timed out".

in lucid too

bam,

I've tried it and didn't work. Maybe I need to install some package or configure something else.

I'm running Ubuntu 10.10 64 bits and I put the computer in S3 through SSH using this command (after a "sudo su"):

echo -n mem > /sys/power/state

I could see that the system went in sleep and then I start to press the buttons on the A2DP device, but the computer remains in sleep mode. The only way to wake up the computer was to press the power button.
This is a HTPC without keyboard and mouse.

My dongle is: http://www.sabrent.com/category/wireless/BT-USBT/
My A2DP device is: http://cgi.ebay.com/Bluetooth-2-0-A2DP-AVRCP-Stereo-Portable-Music-Receiver-/170620137671?pt=PDA_Accessories&hash=item27b9c0b0c7

This dongle is working well. It's working too after the computer went back from the sleep mode. I'm telling this because I read somewhere that using "usbcore.autosuspend=0" is a workarround, but this dongle doesn't need it.

If you need something else or do a more test, please let me know.

After opening up one of my dongles with a screwdriver, I discovered that there is a marking on the board "AS3620QA1". This appears to be a code for Accel Semiconductor, so the devices that are causing an error may not be made by Cambridge Silicon Radio after all, even though the devices list as Cambridge Silicon
Radio through lsusb.

Dear Mark,
I am sorry I cannot open my dongle with a screwdriver, it is the only one I have. But my dongle seems to work and it says that is a

ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth

"The only problem" is that once is connected does not appear as a possible output of sound.
I am using ALSA.
Does this information help to solve this bug?

I'm fighting the same issues with the same dongle. Mine looks exactly like the Sabrent unit, except the Sabrent name is missing. http://www.sabrent.com/category/wireless/BT-USBT/

Linux lapdog 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:45:36 UTC 2010 x86_64 GNU/Linux

Here's the interesting part. If I plug the dongle into my laptop while my Microsoft Bluetooth Mouse is trying to associate, I can pair with the mouse, and everything works OK. But if I reboot, move the dongle, etc., then things don't work any more until I put the mouse back in pairing mode, plug in the dongle, and re-associate them. When the Linux bluetooth stack is loading after the dongle goes in, apparently the "hey, this device is trying to associate" message causes the software not to use the code that causes the error.

It's quite disappointing that all over the web, people report these issues, the hardware works fine in that other OS, but 3 years later we have no fix for LInux.

Hi to everyone, (for Gustavo... I sent you a message abput the same argument... sorry for the duplication)

I hope there are new about this bug

I am using a board (VDX6318D) by Icop Technologies with their linux 2.6.34.1-vortex86-sg.
The dongle I use is "Sena Parani UD100" (that uses Cambridge Silicon Radio).

On board there are 4 USB (2 for each internal hubs), one of this USB are used by internal sound device. I install bluecove-gpl-2.1.0 and bluecove-2.1.0. When I plug 2 of UD100 they works fine, I cannot use 3 dongle togheter because the third does'nt work.

Using hciconfig I have this message:

hci0: Type: BR/EDR Bus: USB

 RX bytes:957 acl:0 sco:0 events:26 errors:0
 TX bytes:358 acl:0 sco:0 commands:26 errors:0

You can see that the hci0 is DOWN, without address and with TX errors, hci2 is fine but with 2 errors (after this it seems work always fine) and hci3 is fine.

I have to use three dongle because I need perfomance to push bluetooth message to many mobile phone and to listen for receive message by other many mobile phones. In future I want use every 4 usb for dongles (I can disable sound device).

I excanged the dongle plugged many times and using other dongle UD100 and also other device with Cambridge Silicon Radio, the problem is the last dongle I plug in a pair of USB of the some internal hub (the dongle in the other hub is always alone, in the example of hciconfig it is hci3). I use other identical board (VDX6318) and I exchange cable, disk on chip, I'am sure I don't have problem with hw. The incredible things is that i plug other dongle "not with Cambridge Silicon Radio" and they works fine with the other 2 UD100.

Thanks in advance

Confirming the bug in Ubuntu 11.10. My system even hangs during an attempted file transfer. It requires a hard reset, not even the magic SysRq key works.

Bus 004 Device 014: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Dear all,
I would like to add a piece of information. This dongle Bus 002 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) did work in Ubuntu 10.04 LTS, I cannot tell you the uname then, because I did not know to use this command then.
It was during one security update that stopped working. I update to Ubuntu 10.10 with the hope that this would work but it did not.
Maybe someone could check if using 10.04 helps to solve this problem.
I am studying Linux command to be able of doing a downgrade, but still did not find the way.
I may be trying a fresh instalation of the Live CD 10.04 LTS
I will let you know.

I am seeing the same issues on Ubuntu 11.04

Linux Mint Debian Edition fixed the issue, but it is still a problem in Ubuntu! :(

The bluetooth radio works perfect in Ubuntu 10.04 - 11.04, but all of a sudden, it doesn't work properly again when I upgrade to 11.10. This problem NEEDS to be fixed, or I am switching to Linux Mint!

i can confirm that the same problem exists with 11.10 and a 3.0.0-17-generic kernel.

am starting to think this device cannot do a2dp at all.

Still a problem on 12.04 - kernel 3.2.0-20-generic-pae.

Exact same behaviour on 10.10 - kernel 2.6.36-020636-generic (from PPA) on totally different machine when I move the adapter to it.

The autosuspend workaround seems to work though.

Spoke too early. It only worked "better" for a while (I could do a few scans), then went back to its own self.

I can confirm #72. It worked fine until I upgraded the Kernel while still on 10.04 LTS. The new version is 2.6.32-40.87, I upgraded from 2.6.32-33.72.

Ubuntu 12.04 now recognizes the bluetooth dongle device, but it usually never stays connected to any device I try to pair, and when I try to send a file from my phone to my Ubuntu PC with the dongle, my phone will ALWAYS give me an error message as "not sent". I have tried other dongles that are the exact same type, and the same thing happens every time. A fix needs to be committed.

I tried these dongles on two PCs running 12.04 and they actually cause the systems to freeze, so that I have to reboot with the power button. They seem to work when I plug them in, but I try to pair them with PS3 controllers using sixad and then the system freezes. This was repeated many times through reboots and on two systems. I have not tried with any other bluetooth devices.

Maarten Fonville, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Please let us know your results. Thank you for your understanding.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug still affects me in Ubuntu 12.10 and 12.04 too.

bug still present: hci0 is UP, but i can't scan for any devices.
Ubuntu 13.04 x64 full updated

also tested with kernel 3.10, issue remains the same :'(

I'm getting similar issues again with my current Bluetooth dongle... Ubuntu, Debian, and Linux Mint all recognize it now, but the connection is very unstable, sending and receiving files may work or may not work, and if they do, the files usually time out mid-transmission.

Jeb E., thank you for your comment. Unfortunately, this bug report is not scoped to you, or your problem.
