I saw there is  /*#include <log.h>*/ available in usb.c 
so you could also try to add :

#define LOG_DEBUG

to the common/usb.c file which should also then enable the debug functions
which then would be output in logging style.

You will need the debug output to to narrow down the issue.

just a guess : 
electrical problem(of the Pi itself)  which could perhaps be fixed by  manipulating the scan delay time .
