This kind of issue was fixed over a year ago by commits 81cac64ba258a and f9f462faa0277. The behavior exhibited by the controllers those commits target is exactly the same as you describe (even the specific error value). Your controller must be somehow different that the quirk doesn't get applied for it. To understand exactly how it's different please provide an HCI trace (btmon or hcidump output) of the failed "hciconfig hci0 up" as well as usb-devices output for your adapter. Hi! Thanks for ready reply! I will take the trace and the infos requested soon as possible (I am not in home now). But, how/where can I see the commits 81cac64ba258a and f9f462faa0277 (see what have changed)? I am new to linux/kernel development. You could do a git clone of the kernel tree and then "git show <commit id>" would work. Alternatively you can see these commits through the web interface: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=81cac64ba258a https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f9f462faa0277 These changes are for HCI_OP_DELETE_STORED_LINK_KEY, if I understand correctly. My problem is for HCI_OP_READ_STORED_LINK_KEY. I think this is a different issue. By the way, the dongle works on CentOS 7 (x86_64) 3.10.0-229.7.2 Later I will provide the btmon/usb-devices infos. Thank you! Sorry, I indeed mixed up these two commands. Sounds like we need a new quirk or need to extend the existing one to cover this second HCI command (the quirk is called HCI_QUIRK_BROKEN_STORED_LINK_KEY so at least the name would cover both commands). FWIW, the kernel code does check whether the controller claims to support this command or not and only issues it if it is claimed to be supported, so in that sense this adapter is quite broken.

It looks like this might be counterfeit CSR dongle since there's a mismatch between the USB bcdDevice value (1.34 == 0x0122) and the LMP subversion reported over HCI (3164 = 0x0c5c). On real CSR controllers these two values should be the same. Ok, but what now? What can I do? I found someone that have the same problem: http://permalink.gmane.org/gmane.linux.bluez.kernel/63817 I think this problem come since the version 4.0 of the kernel, where the command HCI_OP_READ_STORED_LINK_KEY was added. We'll need to come up with patches to set the HCI_QUIRK_BROKEN_STORED_LINK_KEY quirk for this controller and then extend the usage of the quirk to this second HCI command. The main question is whether to apply the quirk against controllers with this specific bcdDevice value or to apply it to any CSR controller where bcdDevice doesn't match the LMP subversion. Either way we'll try to come up with a fix. Ok, thank you! Created attachment 185961 [details]
Patch proposal
Could you please try to see if the attached patch fixes the problem. It only targets the specific LMP version of your adapter.
Of course! But this will take some time. I will need to learn how to apply this patch and compile the kernel (and if can I do it straight on Raspberry Pi 2). Thank you! Created attachment 186141 [details]

The patch for this file failed. I had to do manually.
The patch does not work. The issue was the same (I do not know why. Apparently the patch would have to work). Above are the files modified. The patch failed for the file btusb.c. I had to make the corrections manually. There are some way to know that I have applied the patchs and compiled the sources correctly? Add some log or print to console when the code was executed? //-------------------------------------------------------------------------- #uname -a Linux osmc 4.1.3-osmc-bluetooth-patch-v7 #1 SMP PREEMPT Fri Aug 28 22:20:51 BRT 2015 armv7l GNU/Linux //-------------------------------------------------------------------------- #btmon Bluetooth monitor ver 5.23 = New Index: 00:15:83:16:C0:BF (BR/EDR,USB,hci0) [hci0] 0.024564 < HCI Command: Reset (0x03|0x0003) plen 0 [hci0] 8.177020 > HCI Event: Command Complete (0x0e) plen 4 [hci0] 8.740693 Reset (0x03|0x0003) ncmd 1 Status: Success (0x00) < HCI Command: Read Local Supported Fea..

/* Fake CSR devices with broken commands */
if (bcdDevice <= 0x100)
hdev->setup = btusb_setup_csr;
Since the bcdDevice value of your adapter doesn't match that condition the btusb_setup_csr() function I modified will never get called. Let me try to create another patch.
Created attachment 186161 [details]
Patch proposal 2
Please try with this. It will probably again not apply cleanly since I do these against the bluetooth-next tree which is probably a bit different from yours.
Good news!! #hciconfig hci0: Type: BR/EDR Bus: USB BD Address: 00:15:83:16:C0:BF ACL MTU: 672:4 SCO MTU: 48:1 UP RUNNING RX bytes:484 acl:0 sco:0 events:20 errors:0 TX bytes:324 acl:0 sco:0 commands:20 errors:0 The patch works, but I had to modify the line (btusb.c): if (bcdDevice <= 0x100 || bcdDevice == 0x132) To: if (bcdDevice <= 0x100 || bcdDevice == 0x134) The bcdDevice field is 1.34 and not 1.32. Thank you very much! Good to hear that it works. I've sent the patch (split into two separate commits) for upstream inclusion to the linux-bluetooth mailing list. Do not forget to modify the patch with the correct bcdDevice value (0x134) in the if statement ( if (bcdDevice <= 0x100 || bcdDevice == 0x134 ). Thanks! PS: I have to modify the status of the bug (RESOLVED - PATCH_ALREADY_AVAILABLE) or is up to you? The patch doesn't work for me. Where can I find the bcdDevice value? (In reply to Norbert from comment #21) > The patch doesn't work for me. Where can I find the bcdDevice value? You should be using the patches I sent to linux-bluetooth, the one here had the wrong bcdDevice value. You can see the bcdDevice value e.g. with 'lsusb -v' - if your device is the same one the value should show as 1.34 (i.e. 0x134 in hex). OK, I have 1.34 too. Do I need kernel 4.2? I tried it with 4.1 (Ubuntu x64).

The patch does not worked straight for me too for the file btusb.c. I had to modify this file manually. If your btusb.c is the same as mine, here is what to do:
The original source is like this:
// Line 1356:
if (!rp->status) {
if ( (le16_to_cpu(rp->manufacturer) != 10) {
/* Clear the reset quirk since this is not an actual
* early Bluetooth 1.1 device from CSR.

clear_bit(HCI_QUIRK_RESET_ON_CLOSE, &hdev->quirks);
//---------------------------------------------------
Change it to:
// Line 1356:
if (!rp->status) {
if ( (le16_to_cpu(rp->manufacturer) != 10) ||
( le16_to_cpu(rp->lmp_subver) == 0x0c5c ) ) {
/* Clear the reset quirk since this is not an actual
* early Bluetooth 1.1 device from CSR.
*/
clear_bit(HCI_QUIRK_RESET_ON_CLOSE, &hdev->quirks);
As well the line 3218 must be modified from this (file btusb.c, function
static int btusb_probe(struct usb_interface *intf, const struct usb_device_id *id) ):
// Line 3218
/* Fake CSR devices with broken commands */
if (bcdDevice <= 0x100)
hdev->setup = btusb_setup_csr;
set_bit(HCI_QUIRK_SIMULTANEOUS_DISCOVERY, &hdev->quirks);
//---------------------------------------------------
To This:
// Line 3218

if (bcdDevice <= 0x100 || bcdDevice == 0x134)
hdev->setup = btusb_setup_csr;
set_bit(HCI_QUIRK_SIMULTANEOUS_DISCOVERY, &hdev->quirks);
Thanks for the advice. The new modules are running and my mouse is working.
