Just to close the loop, I've just made fresh SD and USB boot disks from the latest current Mate 20.10 image and both don't have working Bluetooth, Ive updated both with the ppa and now both do work and I can use mouse and headphones with no problems. I have no idea why my original USB boot of Mate 20.10 didnt work after patching, there must be another problem with it as well, my apologies for any confusion caused by that.
Martin and Alan have been nagging us 'ordinary' people to get involved and contribute where we can to help you out if possible, that's all I was trying to do. Thanks for the patch, hope you get it upstreamed, etc OK.

[Test Case] * Boot the Ubuntu Desktop for Pi image on a Pi 400. * Start the Settings application and switch to the Bluetooth tab * Verify that Bluetooth is not enabled and attempting to activate it fails * sudo add-apt-repository ppa:waveform/pi-bluetooth * sudo apt update * sudo apt install bluez * sudo reboot * Start the Settings application and switch to the Bluetooth tab * Verify that Bluetooth is active and that Bluetooth devices (e.g. mice, mobile phones, headphones, etc.) can connect and operate correctly [Regression Potential] Extremely low (on groovy in particular, this has the same version of bluez as hirsute). The only significant risk is to non-Pi platforms or dongles which also use the Broadcom 43xx (or Cypress 305) chips for Bluetooth which might be inadvertently affected by these patches. [Original Description] The new Pi 400 has a slightly different Wifi/BT chip to the Pi4. Whilst wifi works happily, Bluetooth fails to operate. This doesn't appear to be an issue with either the firmware (the latest versions from upstream Raspbian have been tried), or the kernel (a known-good raspi kernel has been tested under Ubuntu), but with Bluez itself. Specifically, tracing the initialization with btmon on Raspbian and Ubuntu, the stack consistently fails when attempting to "Set Default PHY" on the latter. Curiously, under Ubuntu the adapter also appears to lack a MAC address.
