This is after using the Opie applet to eject the card.

The card isn't working properly, it appears to initialize but it can only scan, connection attempts time out with an I/O error. It is a Belkin Bluetooth CF card,

Code: [Select]

root@poodle:/etc/bluetooth# cardctl info
PRODID_1="CF CARD"
PRODID_2="GENERIC"
PRODID_3=""
PRODID_4=""
MANFID=0279,950b
FUNCID=2
It is identified as a 'Compaq iPAQ Bluetooth Sleeve' by Opie and all initialization is done by pcmcia-cs and friends (e.g. nothing manual).

If I down the hci0 interface ('hciconfig hci0 down') it will not come back up: 'Connection timed out (110)'

It has worked properly in the past, most recently with stock OZ 3.5.4.2-rc2. I'd like to stick with the Hentges ROM because it fixes a number of bugs for me on recent OZ firmwares.

Strange, replacing bluez-utils-dbus with bluez-utils-nodbus seemed to fix all the problems. I can use my phone now and ejecting the card does not hit a kernel BUG()

[lardman]

I thought Opie was supposed to have the nodbus one by default?

Anyone?
