The previous mail was a wrong file. Here is the original Raphael report


Hello,

[1.] One line summary of the problem:

AR9462: ath3k and btusb: support for device 04ca:300d makes it disconnect/reconnect indefinitely


[2.] Full description of the problem/report:


I have an Acer Aspire V3-371-31KW with the following Bluetooth device:

    Bus 002 Device 094: ID 04ca:300d Lite-On Technology Corp.

Support for this device has been added in kernel 4.1(.2?) with these three following lines:

in btusb.c:
    { USB_DEVICE(0x04CA, 0x300d) },

in ath3k.c:
    { USB_DEVICE(0x04ca, 0x300d), .driver_info = BTUSB_ATH3012 },
    { USB_DEVICE(0x04ca, 0x300d), .driver_info = BTUSB_ATH3012 },


However, on my computer, it causes a never ending loop of the following:

[10878.667417] usb 2-5: USB disconnect, device number 61
[10879.002466] usb 2-5: new full-speed USB device number 62 using xhci_hcd

[10880.650806] usb 2-5: New USB device found, idVendor=04ca, idProduct=300d
[10880.650816] usb 2-5: New USB device strings: Mfr=0, Product=0, SerialNumber=0

This loops makes the computer's boot take ages and Bluetooth is obviously not working.

The disconnection seems to happen after the call to ath3k_switch_pid. The disconnection loop, however, doesn't happen if ath3k_load_firmware is commented out in the ath3k_load_patch function.

See the last section for a workaround.

[3.] Keywords (i.e., modules, networking, kernel): ath3k, btusb, 04ca:300d, disconnect loop



[4.] Kernel version (from /proc/version): Linux version 3.13.0-24-generic (buildd@panlong) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014


I tried this in Linux 3.13, 3.19 and 4.1, but it should be true for any kernel after 3.13.

[5.] Output of Oops.. message (if applicable) with symbolic information
     resolved (see Documentation/oops-tracing.txt)

Not concerned

[6.] A small shell script or example program which triggers the problem (if possible):

Not concerned

[7.] Environment: Kubuntu and Mint KDE on an Acer Aspire V3-371-31KW

[7.1.] Software (add the output of the ver_linux script here)

If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

[X.] Other notes, patches, fixes, workarounds:

A workaround to this bug is to blacklist ath3k and btusb, and have two versions of them:

1) The patched versions, which contains the following lines:

in btusb.c:
    { USB_DEVICE(0x04CA, 0x300d) },

in ath3k.c:
    { USB_DEVICE(0x04ca, 0x300d), .driver_info = BTUSB_ATH3012 },
    { USB_DEVICE(0x04ca, 0x300d), .driver_info = BTUSB_ATH3012 },
2) The unpatched versions, same modules without these lines.

The workaround is to insmod the patched versions (which load the
firmware), rmmod them after a second, and insmod the unpatched versions.
 After that  Bluetooth is working until next computer suspend or halt.
The firmware is not kept loaded after suspend or halt, but it is kept
loaded after a reboot. Using the unpatched versions without the firmware being loaded makes Bluetooth look activated but unusable.

I also noticed that iProduct = 0 for the 04ca:300d device.

This is my first bug report to the kernel, so please tell me if I did anything wrong.

Cheers,

Raphaël.
