The adapters I'm familiar with are found at
http://owfs.sourceforge.net/adapters.html
Simple question, do you have permission to access the serial port?

FYI:
system/bus shows the following:
address.All = /dev/ttyS0
address.0 = /dev/ttyS0
ds2404_compliance.ALL = 0
ds2404_compliance.0 = 0
name.All = Bad Adapter
name.0 = Bad Adapter
overdrive.All = 0
overdrive.0 = 0
version.All = 10
version.0 = 10
And statistics/errors:
BUS_detect_errors = 1
BUS_read_timeout_errors = 1
BUS_reconnects = 1
BUS_reset_errors = 7
BUS_short_errors = 1
DS2480_sendback_cmd_errors = 1
The other errors are all 0.
I think there is an issue with my adaptor (as indicated by
BUS_short_errors), or do I need to tell OWFS which adaptor I have?
