11.10 USB bluetooth adapter not detected on boot, works if plugged in after startup

If you boot then run:

sudo modprobe -r bluetooth; sleep 2; sudo modprobe bluetooth

Does the device work without unplugging it? If so, we can make this happen at boot esily.

Hi and thanks for your answer! I get "Fatal error: module bluetooth is in use" when trying this.

As lsmod tells me rfcomm and bnep are using the bluetooth module I also tried modprobe -r on those first. I can remove rfcomm but not bnep as I get the same "Fatal error: module bnep is in use" if I try that.

ok try:

sudo modprobe -r hidp
sudo modprobe -r btusb
sudo modprobe -r rfcomm
sudo modprobe -r bnep
sudo modprobe -r bluetooth
sudo modprobe -r btusb
sudo modprobe bluetooth
sudo modprobe btusb

Does it now work, we just need the command that makes it work really. Have a play yourself, you get the idea. The names on the list to the right in your output use the module on the left.

I've messed around with removing these modules - all of them except for bnep and bluetooth can be removed, but even if i remove all the others first it will not let me remove the last two. I also tried

rmmod bnep ("Fatal error: module bnep is in use")
rmmod bluetooth ("Fatal error: module bluetooth is in use by bnep")

I also removed Blueman from startup programs and uninstalled Bluewho, rebooted and did it all over again. Still no luck though.

Can you give the output of:

lsb_release -a; lsmod

Thanks

Try:

sudo modprobe -r btusb ; sleep 2; modprobe btusb

Does it make the device work after a reboot?

user@dator:~$ sudo modprobe -r btusb;sleep 2;modprobe btusb
[sudo] password for user:
FATAL: Error inserting btusb (/lib/modules/3.0.0-14-generic/kernel/drivers/bluetooth/btusb.ko): Operation not permitted

I can remove and reactivate btusb using:

sudo modprobe -r btusb
sudo modprobe btusb

although the device is still not activated.

don't know whether this is helpful at all, but here's a part of dmesg right after boot:

oh and before that, also from dmseg:

If I connect the device after boot, and run dmesg right after, these are the last lines:

I'm thinking that maybe there's a way to run the above without actually having to reconnect the device...
