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. > > [3.] Keywords (i.e., modules, networking, kernel): > > [4.] Kernel version (from /proc/version): > > Linux version 3.19.0-031900rc2-generic (apw@tangerine) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #201412290135 SMP Mon Dec 29 01:36:54 UTC 2014 just include the content of /sys/kernel/debug/usb/devices for this adapter. I assume it is connected via USB.
