I might have a problem with changing reference-ril.c. It's not in my Supersonic source tree.
Those sound like radio-related changes. Do I need those if I'm only going to use CDC ACM through the USB port? And the phone will be the gadget or device. The other end is the host USB side. Actually, the other end is a military box, and wants to use CDC ACM, but it's actually not considering it a modem per se. In other words, I can't use programs like Hyperterminal and minicom to test. I hope that makes sense.
