I had to test it now myself again, since I got unsure if I had set outputs via single commands.
Here is a short howto for setting up the LinkUSB with owfs on OpenWRT Backfire 1. install the kernel driver for the FTDI chip on the LinkUSB: root@dir825:~# opkg install kmod-usb-serial-ftdi Installing kmod-usb-serial-ftdi (2.6.32.27-1) to root... Downloading http://downloads.openwrt.org/backfire/10.03.1/ar71xx/packages/kmod-usb-serial-ftdi_2.6.32.27-1_ar71xx.ipk. Installing kmod-usb-serial (2.6.32.27-1) to root... Downloading http://downloads.openwrt.org/backfire/10.03.1/ar71xx/packages/kmod-usb-serial_2.6.32.27-1_ar71xx.ipk. Configuring kmod-usb-serial. Configuring kmod-usb-serial-ftdi. There should now a device ttyUSB0 in /dev 2. install owfs from standard package source: root@dir825:~# opkg install owfs Installing owfs (2.8p4-2) to root... Downloading http://downloads.openwrt.org/backfire/10.03.1/ar71xx/packages/owfs_2.8p4-2_ar71xx.ipk. Configuring owfs. 3. make a directory for the fuse-filesystem. I use 1wire in /mnt root@dir825:~# mkdir /mnt/1wire 4. start owfs like so for example: root@dir825:~# owfs -d /dev/ttyUSB0 -m /mnt/1wire 5. check in the 1wire directory if the bus is up and running root@dir825:~# ls /mnt/1wire/ 01.59A3D5120000 28.1C5015020000 28.2E4115020000 28.487A15020000 28.664515020000 28.893015020000 28.8D3C15020000 28.E35415020000 29.646C08000000 alarm settings statistics system 28.0F5715020000 28.227415020000 28.405C15020000 28.496D15020000 28.764A15020000 28.8C4615020000 28.A04A15020000 28.F13915020000 29.B46008000000 bus.0 simultaneous structure uncached There you go! Now on to Silvios problem: I did set PIO.0 on 29.646C08000000 and ... NOTHING! I cannot set single outputs as well. Writing to 1 to PIO.BYTE works fine though. Output 0 gets switched on, but PIO.0 does not get updated, it stays on 0! So I am confirming the problem!!! Shame on me. My previous test on OpenWRT was not very thorough! Btw., I can read temperatures fine!
