change HCIATTACH_SPEED to 230400 (from suggestion on wiki), but it had no
effect on my problem.

where is this suggestion in the wiki and what did you change it from? I remember Craig had some real trouble with bluetooth adapters becoming unresponsive on certain bps changes. There is some hackery in hciattach or in the kernel so attempting 921k actually stays at a safe 115k
