- Use CLOCK_MONOTONIC instead of CLOCK_REALTIME, because CLOCK_MONOTONIC does not wrap into negative in near future. This fixes any potential problems using "pthread_cond_timedwait()". - Fix a bug where the "libusb_wait_for_event()" function computes an absolute timeout instead of a relative timeout. USB transfers do not depend on this timeout value. - Add dependency towards LibPthread to Makefile, because LibUSB v1.0 needs this library to function correctly. MFC after: 1 week
