Old story, I know, but had the same setup and intention and not enough leisure for recompiling. Tape is ugly :( So just in case somebody might find this helpful, here's what did the job for me:
The plastic cover of the dongle is easily removable with any fine tool. It is simply clipped around the antenna, nothing more than a gentle clap needed.
Once removed, you see the antenna and a small circuit board that essentially is the USB dongle. You can carefully pull this circuit board a bit back until you see the LED (tiny white rectangle between soldering pads).
Carefully grind it down to pieces. Then reattach the cap. Done.
