bluetooth works only after wakeup

Hello everyone,

since the last High Sierra update bluetooth only works after I sent the laptop to sleep and wake it up.

I use a BCM94360CD BCM94331CD for wifi and bluetooth (via adapter in a hp EliteBook 8770w). Before the last update BT worked just fine directly after booting. Now it isn't detected and only shows up after I wake the laptop up from sleep.

Does anyone know how to solve this? Is it even a real BT problem or is it maybe a USB problem (since the BT part of the card is connected via internal USB - other USB components are doing just fine though)?

Thanks in advance!

edit:wrong wifi/bt adapter
