Good question, I didn't have it enabled in my build: # CONFIG_BT_HCIBTSDIO is not set Let me add it and report back.
If so, you'll want to blacklist the SYN43752 chip in the btsdio.ko. Similar to https://github.com/jimmyhon/linux/commit/81c14dc2dea2ceaea8d390188b352d32e278abc8 The original logic was introduced in https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/bluetooth/btsdio.c?id=b4cdaba274247c9c841c6a682c08fa91fb3aa549
I will check, thank you for the pointers! Best regards, Alexey
