Error Module Bluetooth Is In Use By Bnep
with my Trust bluetooth 3.0 USB adapter, which i'm using with a mouse. If i insert the adapter in the usb port after the system has booted, everything works fine. If i boot with the adapter already inserted in the usb port, the led on the adapter doesn't light up and bluetooth doesn't work. If i run lsusb the adapter appears in the list as long as it is connected, even when it is not active/lit up. If I have a usb drive in the port it gets detected automatically, both if it's in before boot or inserted afterwards. I've also noticed that if i run lsmod before and after inserting the adapter i get the following difference (the rest is identical in both cases and deleted here for space reasons: before: user@dator:~$ lsmod Module Size Used by rfcomm 47946 4 bnep 18436 2 bluetooth 166112 10 rfcomm,bnep ... after: user@dator:~$ lsmod Module Size Used by hidp 22862 1 hid 95463 1 hidp btusb 18600 4 rfcomm 47946 12 bnep 18436 2 bluetooth 166112 28 hidp,btusb,rfcomm,bnep ... This led me to try adding the modules missing when the device is not active into /etc/modules, like this: before: lp rtc after: lp rtc hidp hid btusb However, this did not help. Would anyone know how to solve this so that i don't need to take out and reinsert the adapter after every boot?

If so, we can make this happen at boot esily. Axel Kardell (axel-kardell) said on 2012-01-20: #2 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. actionparsnip (andrew-woodhead666) said on 2012-01-20: #3 ok try: sudo modprobe -r hidp
you running Debian Squeeze Linux (as server Apache, MySQL, Qmail etc.) on brand new purchased hardware with bluetooth support; you will notice default Linux kernel will detect and load modules for Bluetooth This would not be a problem only if Bluetooth does not pose possible errors or (even at cases even maybe system hangs ups?). The https://answers.launchpad.net/ubuntu/+question/185303 actual reason in my case to want to disable bluetooth on a productive Linux server operating like host was I found out in dmesg produced output, some errors related to Bluetooth, here they are: root@deb:~# dmesg|grep -i 'call trace' -A 8

If I'm not mistaken, this BT device should be supported by "hci_usb" driver. Do you have the driver enabled in the kernel? Can you modprobe it manually?EDIT: The driver's name is actually "btusb", I'm sorry for any confusion.
