The driver module is separate from your kernel, but it must have been compiled using the same sources. This means that whenever you upgrade your kernel, you have two possibilities:

1) Download the driver package from Linuxant's web site that corresponds to your new kernel version - if it's a very recent kernel, we might not have released a package for it yet.

2) Use the generic drivers (downloadable from Linuxant's web site) instead of using drivers specific to a single Linux distribution and kernel. To use the generic drivers, the kernel source tree used to build the kernel that you are running has to be installed. When using the kernel supplied by your Linux distribution, you can simply install the "kernel-source" package.

With the generic drivers, you can easily recompile the module after upgrading your kernel by running the following command:

dldrconfig --kernel
