usbfs was removed from linux starting with kernel version 3.5 (July 2012).
Some linux distros with "extended life" support for old kernels
may still allow you to enable usbfs, but it's not a tenable requirement
going forward. Whatever script or component was using this should
be updated to query /sys/kernel/debug/usb/... instead.
