Since latest update 10.13.6 (17G8030), I notice USB 2.0 no more listed in "System Report"\USB:

Don't know if it is related, but my BT is getting also unstable, e.g. even though it is ON at top status bar(also in SysPref BT panel), but it is in fact OFF(cannot airdrop etc).

Anyone notice the same?

I applied Rehabman's USB patch, which should go to HS07, i.e. USB 2.0. Why BT(BCM20702A0) listed under USB 3.0 bus? very strange, I didn't change the patches(or kexts), how could it happen like this?

appreciate any comments/suggestion to solve or to debug.

EDIT @ Oct. 30: It is correct, BT is under USB 3.0 bus.
