No need to rebuild the kernel, Lucas, cd to /usr/src/linux and make -C .
M=sound/usb

This will rebuild the usb sound modules only, which will taint the kernel
but at least will spare you some time and some reboots.

After building the modules, modprobe -r the modules you want to reload,
copy the relevant .ko files to the proper place inside /lib/modules and use
the depmod command.
