I also true using an old bluetooth usb dongle. I used it on the asus
T300, but that made no difference. I also tried it on my dell 1558
laptop, with 16.04 (64-bit) and 15.10 (32-bit with bluez 5.35). The
16.04 test was basically the same as on the asus. The 15.10 test was
different in detail, but still showed the docking station briefly
connecting, but disconnecting a second or so later.

All tests produced the "not enough handles" message from bluetoothd. Is
anyone successfully using bluetooth with these later ubuntu kernels?
