Training on the kernel is probably necessary, and the Linux foundation course is expensive... but LFD430 is what you are seeking. Primarily, there were many trends in the kernel module structures, and a lot of deprecated apis. If you just read the code, you are guaranteed have issues with the legacy code peppered in the module source. Essentially, if you just need a USB workaround, than a user space program with libusb will greatly simplify your life. =)
