The is a test of a 1-Wire network.
The test hardware
1 iButtonLink 1-Wire USB Interface
6 iButtonLink T-Sense temperature sensors
1 Hobby Board 4 channel hub.
The test software
DigiTemp v3.6.0
Xubuntu 13.04
AXIRIS.eu - (owhbh4) 1-Wire Software v1.3.1
This first test is with all of the sensors plugged into the 4 channel hub. The 4 channel hub channels are off by default.
1. -i Initialize .digitemprc file, search the bus for all supported
devices.
$ digitemp -s /dev/ttyUSB0 -i -c ./digitemp.conf

2. -w Walk the full device tree and display the serial number and type
of all devices detected on the bus.

Note: The 4 channel hub (EF2E672015000017) is detected during the walk.
3. -a Read all sensors.
-q Quiet output, no copyright banner.
$ digitemp -s /dev/ttyUSB0 -a -q -c ./digitemp.conf

Sep 19 18:01:44 Sensor 1 C: 20.44 F: 68.79
$
Note: We read the 2 sensors passed through and unaffected by the
4 channel hub. The 2 sensors are connected serially with the
green wire and are not shown in the photograph.
This second test is the same as the first test but with all
4 channels turned on.
4. With the owhbh4 program we set all 4 channels of the
4 channel hub on.
$ ./owhbh4 -serial /dev/ttyUSB0 ds9097u -id EF-00001520672E-17 -pr -setcfg m -setch on 1 2 3 4
$
5. Again we initialize the digitemp config file.
$ digitemp -s /dev/ttyUSB0 -i -c ./digitemp.conf

$
Note: All sensors were read.
8. Turn all 4 channels off.
$ ./owhbh4 -serial /dev/ttyUSB0 ds9097u -id EF-00001520672E-17 -pr -setcfg m -setch off 1 2 3 4
$
Note: With owhbh4 we must specify which channels we want turned
on or off.

I forgot to mention how I found the "-id EF-00001520672E-17" for owhbh4.

I'm trying this out... but so far haven't gotten far.
I get:

And:
]# ./owsenum -serial /dev/ttyS0 ds9097u -hub -dst
Enumeration time: 1052 ms
Devices enumerated: 0
01: DS9097U (path /dev/ttyS0)
01: DS2480
So, it seems ows can't see the hub? I'm using a serial-2-ethernet adapter picked up from iconnect back in the day. It's running on /dev/ttyS0
I know digitemp is working since it's a system that's been in production for several years now. Recently I picked up this hub, and tried to expand and re-organize the 1-wire network... but I can't get the hub to work. (i really really wish they'd just ship the hub with the darn ports on... )

digitemp doesn't support the Hobby Boards hub.
