Hello. My wireless chip is defined as: Intel Wireless AC 9260 (different network, version 0x29) on pci1 dev 0, function 0 not configured.
When booting the system I always got an error: CommanComplete opcode failed (003|0003) (status=0x01). When I tried to manually raise the interface via `btconfig ubt0 up`, I received the error: btconfig: SIOCSBTFLAGS: Resource temporarily unavailable. I decided that my chip was not working until I reboot into Windows and then back into NetBSD, after which the bluetooth worked. How so? :) I suspect that the firmware is missing and Windows uploads it. If so then I don't understand how it survives the reboot.
