The path /usr/src/linux is the standard path where kernel sources live in a linux system. Depending on your distribution you can install linux kernel sources with your package manager, or you go to http://www.kernel.org and download and extract one. Download a kernel with git One of the most powerful ways is to download a kernel with git as super-user ...

On Arch, Ubuntu/Debian family and the later RedHat/CentOS/Fedora systems, you blacklist the module by adding bluetooth.blacklist=yes at boot time. If you're using RedHat 6 and it's derivatives you can use the rdblacklist=bluetooth boot option to blacklist a module (assuming the module is called bluetooth on these systems).

I'm trying to do the same thing you are: get a 3G/4G modem to work on the ARDrone2. I'm not as far along as you are though, I only just managed to get my hands on the toolchain, and my first few attempts at a hello world have crashed. I don't really have an answer, only an idea. I did a quick google on your log messages, and I found this: ...

As per my current understanding. No one (user space script) is actually calling modprobe\ insmod to get these CAN drivers inserted, this is because they are Platform Devices. This is identified by: The alias: platform: information from the modinfo command The source code for the c_can_platform which defines the c_can_plat_driver as a ...

If you'd like to avoid "permission denied" errors and search recursively the whole Android filesystem, you'll need to have a "rooted" device. Afterwards, having a rooted device, you may install any Terminal emulator application, run su and run find command. E.g., you'd like to find all files with .ko extension, so please run: find / -name "*.ko" in ...

As mentioned by Code_cynic, the double underscore means that is is reserved (the same for keywords with one underscore followed by a capital letter): http://stackoverflow.com/a/10687114/2915175 The explanation of the __init macro can be found here and it expands to a __attribute__: http://stackoverflow.com/a/8832166/2915175

Some devices lose firmware on suspend, but btusb does not notice that. For some devices it has been fixed in newer kernels. The fix is that the module is automatically bumped, like you do manually on resume. Anyway it is a kernel bug. You can test newer kernels or report it upstream. A workaround is to make a wake up script that will restart it on ...

It's an alternative to "using a distribution [...] package", which is synonymous with having "the configuration and header files" available. You should include a .config before you do this. Most distro kernels have this available in /proc/config.gz; copy that into the top of the source tree and gunzip -c config.gz > .config This will only work if ...
