Per this link we need to upgrade Raspberry Pi firmware first:

root@raspbx:/etc# sudo rpi-update

Ran into this problem:

Jan 19 22:00:15 raspbx OWFS[1683]: DEFAULT: owlib.c:(208) Cannot open USB bus master

Jan 19 22:00:15 raspbx kernel: [  225.759441] usb 1-1.2: usbfs: interface 0 claimed by usbfs while 'owfs' sets config #1

Update 1/9/2017

Reinstalled raspbx, so now need resinstall owfs packages and get this error:

Updated the firmware again, not sure where firmware is stored - installed new os.  Looks like this version is different from the version above updated last time:
