I have a Mac Pro 4,1, upgraded to 5,1 and with a Saphire RX 580 card ran Mojave for some years without issue. I later replaced the original BT and WiFi cards with a newer combined one (BCM94360CS) from a MacBook Pro and had Handoff, Watch unlock etc working fine.

Finally decided to use OCLP to update to Monterey and put all that on a 500 GB NVMe stick on a Lycom PCIe card. Everything worked.

Recently decided to replace the 500 GB NVMe with a 1 TB. This was a Sabrent M.2 stick (recommended as fully working in Macs) and also swapped out the Lycom PCIe for a Sabrent one, so I would have a complete spare NVMe/PCIe solution.

Used OCLP 2.4.1 to orchestrate a fresh install of Monterey 12.7.4 (latest installer available) on the new 1 TB NVMe drive, followed by a migration from the old NVMe to copy the users.

Taken a while, but all up and running with Apple USB keyboard and mouse. However tried to connect a BT Magic Mouse and realised there is NO BT. Cannot switch it on and System Information/Hardware/Bluetooth just comes up blank. Literally. Spinning progress wheel but just blank.

Where's Bluetooth gone?

It occurs to me that maybe some drivers/kexts were previously required to enable this BT/WiFi module, but OCLP doesn't know this as it just builds for a Mac 5,1. Or is that just a fanciful memory and I had to do no such thing. I cannot now remember. 🤬

I checked OCLP's root patches but it says nothing is required.

So I'm a bit stumped as to why I have no BT when previously this Mac, ran Monterey via OCLP with no such lack. The only changes are a larger NVMe on a different PCIe card and OS version is now 12.7.4 instead of 12.6.? There's nothing that jumps out as causing this issue, unless I have missed some driver and/or kext.

Anyone any clues abut this?
 
Apple rebuilt the BT stack for Monterey, which has caused problems for 3rd party BT dongles on anything after Big Sur. The last time I tried to get a BT 4 dongle to work, it worked perfectly up to Big Sur, and did squat in Monterey or later. In this case, the default BT card still worked fine, the problem was inability to switch to a BT dongle.

For your problem, I suggest reinstalling the factory BT module, then reinstall OCLP to pick up the hardware change. Followed by redoing root patches. Then swap the factory BT module for your upgrade.
 
Except it's not a dongle I'm using. Or anything third party. It's an Apple BT/WiFi card, just not one originally supplied in a Mac Pro 5,1.

Also, this Mac ran absolutely perfectly with this exact card - for years.

Just rebooted (5 times with OCPR to clear NVRAM) and although System Information is showing the hardware, I cannot turn it on.
 
Apple deprecated and started removing support for the ancient MacPro5,1 OHCI USB controllers since Big Sur, each subsequent release is worse for anything that is connected via USB.

If you install a USB 2.0 hub (EHCI) between the D+ and D- of the BT card and the USB connection on the backplane you'll overcome the missing OHCI support, since EHCI is still supported.
