What's the symptom? what do you mean by stopped to work?

Can you provide me output of "hciconfig -a"?

And if possible enable dynamic debug for your kernel, mount the debugfs
and then

echo -n "module btusb +p" > /sys/kernel/debug/dynamic_debug/control
echo -n "module bluetooth +p" > /sys/kernel/debug/dynamic_debug/control
