Exclamation bluetooth device not detected slack14


hello all,
i am more of a forum voyeur, but i haven't found a suitable solution to this issue. bluetooth worked with fedora i was running before, and i am a single linux system.

anyway, having issues getting my bluetooth up and running... set my rc.bluetooth to exec and started it, but i seem to have an issue with hciconfig finding my device. it doesn't return anything actually. when i pull ifconfig, there is an eth0, lo, irda, but no hci0 i have been promised

i have a thinkpad t60 and it has built-in bluetooth. wireless works as expected, no problem with brightness controls or any other acpi-type function i have tried. checked my bios and bluetooth is activated.

so here is what i have found and frankly have no idea how to deal with: lsusb doesn't show a bluetooth adapter has been found. it sees my fingerprint reader and root hub devices. any suggestions would be greatly appreciated.

thanks,

Just use hciconfig but not ifconfig. If you don't see it, try lsusb or lsusb.py to see if your bluetooth is activated.

hey guanx,

i ran lsusb, and don't see anything related to a bluetooth adapter. here is the output, and this is where all the howto's lose me. any suggestions? thanks!


Code:
Bus 005 Device 006: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
here a tail from dmesg starting it sees something with the bluetooth:

Sorry, I missed your lsusb test in the original post.

Did you try enabling it according to this page: http://www.thinkwiki.org/wiki/ThinkP...te_%28BDC-2%29

so i appreciate the help thus far, but...

i have been trying to load the thinkpad_acpi.patch file suggested by thinkwiki for a couple of hours now, but i don't feel its going to work. its all tied to a 2.6 kernel, and i am running the 3.7.1-smp as returned by uname -r. it seems this kernel version has some built in acpi support, but not for the bluetooth device. should i revert to a previous kernel?

thanks!
