Comment 12 for bug 554099

It's been too long since I did a kernel compile. I installed the linux-source package, expanded it, configured the kernel (I just accepted the defaults), patched with the patch from http://www.codon.org.uk/~mjg59/gobi_loader/kernel_patches/, compiled, and copied options.ko, qcserial.ko, and usb_wwan.ko to /lib/modules/`uname -r`/kernel/drivers/usb/serial, and when I do `sudo modprobe qcserial` I get an error about unknown symbols from usb_wwan. I tried `sudo modprobe usb_wwan` but I get an error that usb_wwan is an unknown module. What steps am I missing? Could someone kindly post step-by-step instructions?
