    What happens to hub if plugged into ethernet port accidentally?

    FWIW: It wasn't that hard to fix. I had to replace the diode in the 12v path and the DS2408 chip and replace the burned trace with a piece of wire. Three people pointed out to me that this is why its always a bad idea designing interfaces using common connectors in ways which aren't compatible...

    What happens to hub if plugged into ethernet port accidentally?

    I answered my own question by taking it apart. A couple traces are fried between the 12v regulator and the 8-pin DS2408 chip right next to it. I think I might have a replacement chip around here, but I wonder if its worth the trouble to replace it? A lot more could have been taken out along...

    What happens to hub if plugged into ethernet port accidentally?

    I was troubleshooting a PC on my way-overcrowded workbench and grabbed what I thought was a spare ethernet cable from an 8-port router I keep sitting there for that purpose. Unfortunately, it was actually, a spare wire plugged into my 6-port master 1-wire hub that I had just unplugged from a...

    Linux software that talks to 6-channel master hub?

    Does anyone know if there's a way to mount this filesystem with userspace permissions? [edit] Never mind - I just figured it out. Sorry about wasting bandwidth. For anyone following the thread, its --allow-others on startup, and uncomment the similar option in /etc/fuse.conf Jeff

    Linux software that talks to 6-channel master hub?

    Your suggestion worked: it mounts just fine with this command: /opt/owfs/bin/owfs -d /dev/ttyS0 -m /mnt/1wire ls -l /mnt/1wire drwxrwxrwx 1 root root 8 2008-10-13 19:52 1F.43D903000000/ drwxrwxrwx 1 root root 8 2008-10-13 19:52 1F.59D603000000/ drwxrwxrwx 1 root root 8 2008-10-13 19:52...

    Linux software that talks to 6-channel master hub?

    Hi, I'm working in the Linux world, new to 1-wire, bought a 6-channel master hub and some sensors and can't figure out how to talk to this hub. I installed owfs but it looks like it only knows how to talk to 9000 series parts, not this hub which goes through a regular old COM port via the maxim...
