I assume you have at least 1 USB device while trying this. I don't remember
exactly, but while trying within Linuxolator, you may need devfs/procfs to
be mounted under Linuxolator's root directory.

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.
