Hi Miguel,
>>> [1.] One line summary of the problem:
>>>
>>> 0489:e062 [Sony VAIO SVF1531C5E] Bluetooth adapter does not see BT devices
>>>
>>> [2.] Full description of the problem/report:
>>>
>>> The Bluetooth adapter is detected and apparently working but, when executing "hcitool scan", the device list is always empty: it cannot see any BT device around.
>>>
>>> But, if I boot into Windows just before booting into Linux, the adapter works perfectly and it sees all BT devices. It seems Windows driver is performing some activation to the BT adapter.
>>>
>>> Test case:
>>> Step 1: power on the Sony VAIO SVF1531C5E and boot into Linux.
>>> Step 2: while having around one or more devices with BT enabled and visible, type "hcitool scan" and wait for a few seconds just to see that nothing gets listed.
>>> Step 4: reboot the laptop and boot into a Windows partition (mine is Windows 8.1 x64).
>>> Step 5: wait until it is completely booted, then just reboot into Linux again.
>>> Step 6: while having around one or more devices with BT enabled and visible, type "hcitool scan" and wait for a few seconds just to see all of your devices correctly listed this time. You will be able to pair and use them later without any issue.

this one is listed as loading firmware patches if they are provided.
/* Foxconn - Hon Hai */
{ USB_VENDOR_AND_INTERFACE_INFO(0x0489, 0xff, 0x01, 0x01),
.driver_info = BTUSB_BCM_PATCHRAM },
The only thing you have to do find the right *.hcd file and put under /lib/firmware/brcm/ so it can be loaded. I bet if you call dmesg and look at the log of the driver it will even mention something about the firmware file.
Some of the Broadcom dongles are pretty much broken. They will not work when you do not patch the firmware to fix their bugs.
Regards
Marcel
