Bad Linux ARM zImage magic

Well the next issue I ran into was with the USB bluetooth adapter. I have two, both are based on Broadcom chipsets the BCM2046 and BCM2070A0.

Digging deeper into things these are the messages I’m getting-

from dmesg

It’s the same issue for the Rocketfish adapter with the BCM2046 chip.

Do I need to upload firmware to the BCM2046 or BCM2070 during intialization in order to be able to use them? Is it available to us?

The Rocketfish adapter was connecting to my iPhone in v3.8.
