My understanding and from looking at trace is that if we cannot find it in /compat/linux we ale search in /; so no need for an extra mount unless maybe you run chrooted. > So you'll have to figure this out. > > Does it return with 0 exit code? > > If not, lsusb should be simple enough to let you place printf() all over the > place and understand out when it's failing. For me the problem was a clock_gettime() call in the libusb which my glibc did not provide. That made all things fail (silently) until I used linux “rtld" tracing to see the unresolved symbol from libusb/the commercial 3rd party software dynamically loading libusb. — Bjoern A.
