Problems with CF bluetooth

[Pavel Machek <pavel@ucw.cz>]

Hi!

I have some problems with Billionton CF card: if I insert card,
hciattach to it, eject it, hciattach again, I get an oops.

[Pretty recent kernel: Linux amd 2.6.14-rc2-g5fb2493e #106 Thu Sep 29
01:35:25 CEST 2005 i686 GNU/Linux]

Another problem is that... it works well on my PC. When I try to do
the same hciattach on sharp zaurus handheld, I get

(I had to hack serial driver a bit to default to 921600 bitrate; it
does not have setserial).

# hciattach -s 921600 /dev/ttyS0 bcsp
BCSP initialization timed out
