Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Firmware is needed from Broadcom Windows driver and converted with Jesse Sung's hex2hcd program

Some info http://unix.stackexchange.com/questions/189790/how-can-i-get-the-bluetooth-working-on-my-lenovo-yoga-3 on how to find the firmware in the windows driver

[Dennis (deki24)]

There was no firmware conversion necessary with Ubuntu 14.10 and 3.16 kernel.

Installed latest upstream kernel 4.0.0-040000.201504121935. Same problem here:

I also updated BIOS to 2.70 without effect.

[Dennis (deki24)]

Not working with 4.0 kernel: "/dev/mem: No such file or directory"

[Dennis (deki24)]

Output with 3.19 kernel:

Dennis, the next step is to fully commit bisect from kernel pre-3.19 to 3.19 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

Thank you for your understanding.

[Jeremy (wa113y3s)]

At one point early in 3.13 kernel and likely 3.16 some of the Broadcom bluetooth were supported due to the following in btusb.c

/*Broadcom devices with vendor specific id */
 { USB_VENDOR_AND_INTERFACE_INFO(0x0a5c, 0xff, 0x01, 0x01) },

Now most kernel versions contain

/* Broadcom devices with vendor specific id */
 { USB_VENDOR_AND_INTERFACE_INFO(0x0a5c, 0xff, 0x01, 0x01),
   .driver_info = BTUSB_BCM_PATCHRAM },

This was added to 3.16.0-34

http://git.kernel.org/cgit/linux/kernel/git/bluetooth/bluetooth-next.git/commit/drivers/bluetooth/btusb.c?id=10d4c6736ea6e6ff293dd588551270bca00ca45d

[Dennis (deki24)]

That commit seems to be the cause of the error message. However I just noticed that bluetooth is still working. I was confused because the indicator icon was gone after 15.04. release upgrade but I was able to start it manually and connection works although the error message is present.

[BarryD9545 (k-barry-x)]

I can send from Ubuntu to a Nexus 5, but cannot send from the phone to Ubuntu, transfer starts, but no "accept" notification comes up.

Setting to always accept has no positive effect.

Pull down from notification shows only "Send Files..." for phone.
 Win7 laptop has no problems sending.receiving, and has all options in menu (Connection, Browse Files..., Send Files...)

Win7 has no problem send/receive to/from phone.
