Jim I have been using the 2412U PLM for a year or so. I run MH on an NSLU2/Debian platform where the PLM and a USB book drive are the only USB devices. The NSLU2 and HDD are on a UPS which is powered through an Insteon 1626 Filter Link, but the PLM plugs directly to the AC outlet. At random times (once in a very great while, weeks, sometimes months apart) something causes the 2412U to move from /dev/ttyUSB0 to /dev/ttyUSB1 and MH communication with the PLM stops. I live in Florida, the land of frequent weather induced interruptions, which I assume are the culprit. Search the forum for "PLM" and for "udev", there are several good suggestions in the past 9 months on how to influence USB device mounting. The PLM appears to use an FTD serial to USB device (try 'lsusb -v') internally. I have not been completely successful recovering automatically from the random event. I implemented the udev suggestions that symlink the PLM to the /dev/ttyUSBx, but you still need to reset the serial interface from within MH (I used the web interface) for full operation to recover. I have currently instrumented the MH code to attempt to detect the 'hung serial' state and automatically do a serial reset of the PLM; still testing. I have also set up an hourly cron to check for the existence of /dev/ttyUSB1; I am considering an automatic reboot when found. A manual reboot has been my typical corrective action. The NSLU2 does not have RS232 ports, only USB. Many folks seem to use UPS powered USB to RS232 external converters and the 2412S, but I suspect that the 2412S might also need a 'serial reset' on occasion. Good luck, please update us with good working solutions. Jim Duda wrote: > > Hello, > > My Insteon PLM has died again. I had one go back in July.
