I’m using a LinkUSB interface… no idea what’s wrong with your setup, but let me
share my configuration.
Here is my owfs.conf:
server: LINK = /dev/linkUSB0
server: port = 4304
server: readonly
server: error_level = 2
server: error_print = 1
/dev/linkUSB0 is a symlink to the actual device. The LinkUSB should appear as
/dev/ttyUSB0 (but as everything USB if you have more than FT232 USB UART
connected it could end up as /dev/ttyUSBx with any x)
$ ls -l /dev/linkUSB0
lrwxrwxrwx 1 root root 7 Nov 15 16:21 /dev/linkUSB0 -> ttyUSB0
$ ls -l /dev/ttyUSB0
crw-rw---T 1 root owfs 188, 0 Nov 16 18:32 /dev/ttyUSB0
Symlink is created by a udev rule, which also sets the device group (for
running owserver as an unprivileged user.)
SUBSYSTEM=="tty", \
ATTRS{product}=="FT232R USB UART", ATTRS{serial}==“here your FT232R serial
number", \
SYMLINK+="linkUSB0", GROUP="owfs"
You can determine your FT232R serial number searching the output of
$ udevadm info -n /dev/ttyUSB0 -a
for the relevant ATTRS lines:
ATTRS{manufacturer}=="FTDI"
ATTRS{product}=="FT232R USB UART"
ATTRS{serial}==“xxxxxxxx”
My linkUSB is the only bus master, so it appears as /bus.0 on owfs, and here is
the printout of the interface tree:
/bus.0/interface/settings/address '/dev/linkUSB0'
/bus.0/interface/settings/ds2404_found '0'

Hope this helps.
