Fix javax.

The correct path for USB raw device nodes (for the past few years)
is /dev/bus/usb

For details about connected USB devices, you can either use the
sub-directories of /sys/bus/usb/devices (each is a device), use libudev
(which also provides notification of new devices) or for minimum effort
read from /sys/kernel/debug/usb/devices which is the same format as the
old file.
