What do you mean by
+       for (reps = 0; reps >= 0; reps++) {
?

If you will not reps is negative.  Roughly it is a loop
that will timeout eventually if a usb debug cable is not present.

So since I didn't know how many loop iterations made sense I allowed
it to loop for 2^31 times or until reps goes negative.

This doesn't work however.  Signed overflow in C is undefined,
and GCC actually optimises accordingly (unless -fwrapv is used).
