I have done the following:

1. dmesg | grep Bluetooth. This reveals the name of the firmware patch 
needed:

[   15.825275] Bluetooth: hci0: BCM: patch brcm/BCM43142A0-0489-e062.hcd 
not found

2. Mounted the Windows 8.1 x64 partition into /mnt

3. find /mnt -iname '*brcm.inf'. This leads to '/mnt/Program 
Files/WIDCOMM/Bluetooth Software/bin/bcbtums-win8x64-brcm.inf', viewed 
it and located the E062 string which leads to the file 
BCM43142A0_001.001.011.0161.0182.hex:

...
%BRCM43142BtAdapter.DeviceDesc%=BlueRAMUSBE062, 
USB\VID_0489&PID_E062       ; Sony 43142A0 combo
...
;;;;;;;;;;;;;RAMUSBE062;;;;;;;;;;;;;;;;;

[RAMUSBE062.CopyList]
bcbtums.sys
btwampfl.sys
BCM43142A0_001.001.011.0161.0182.hex
...

4. find /mnt -name 'BCM43142A0_001.001.011.0161.0182.hex'. Copied the 
'/mnt/Program Files/WIDCOMM/Bluetooth 
Software/bin/BCM43142A0_001.001.011.0161.0182.hex' file into my home dir.

5. Downloaded and compiled hex2hcd (https://github.com/jessesung/hex2hcd 
<https://github.com/jessesung/hex2hcd>). Executed it against the 
BCM43142A0_001.001.011.0161.0182.hex file to get the 
BCM43142A0-0489-e062.hcd as requested by the dmesg message, and put it 
in /lib/firmare/brcm.

6. Reboot.

7. Now dmesg does not show the error "patch 
brcm/BCM43142A0-0489-e062.hcd not found", but the BT adapter is not even 
recognized ("hcitool scan" shows No such device), and dmesg shows this 
error in addition to the "hci0 command 0x1001 tx timeout" one:

[   26.265214] Bluetooth: hci0: HCI_OP_READ_LOCAL_VERSION failed (-110)

8. I rebooted into Linux again (no Windows this time), and the BT 
adapter is now recognized and fully working ("hcitool scan" shows all 
the BT devices around). Dmesg shows no errors this time but this two new 
messages:

[   15.107318] Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=00b6 
lmp_ver=06 lmp_subver=210b
[   15.567138] Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=00b6 
lmp_ver=06 lmp_subver=210b

Thus, there is no need to boot Windows before Linux if the .hcd file is 
present, but you still need to boot Linux twice in order for the BT 
adapter to work properly:

Miguel.
