@Po-Hsu,
It's weird your output shows the btusb is being used...
1, please show me the output of "#modinfo btusb" on the working system 201307-13905 - Dell Latitude 3440
2, I built a testing kernel for Bug #1317453, looks like same issue, could you please take a test? http://kernel.ubuntu.com/~adamlee/lp1317453/
Thanks.
