Hi all,
For the past few weeks, I've been having an intermittent problem with my 2413u. It disconnects and stops responding, the LED goes out, and it gives the following log entries:
2014-10-23 02:54:43.119 Error unknown command bytes received 06 15 (ignoring)
2014-10-23 02:54:51.116 Error PowerLinc not responding -- attempting reset
2014-10-23 02:54:51.375 Power Failure possible power failure
2014-10-23 02:54:55.005 Interface Failure lost connection with interface
After that, I can't enable the interface even after unplugging and plugging it back in.
2014-10-23 05:53:27.132 Application Enabling interface "INSTEON Commands 2.0.5"
2014-10-23 05:53:27.134 Application Starting interface "INSTEON Commands 2.0.5" (pid 27531)
2014-10-23 05:53:29.289 Application Started interface "INSTEON Commands 2.0.5"
2014-10-23 05:53:34.429 Interface Failure failed to establish connection with serial interface PowerLinc Modem on port usbserial-A600exI7
2014-10-23 05:54:30.132 Application Closed connection to PowerLinc Modem
After waiting a while, or trying some more, it starts working again. I'm not sure what kicks it going again but I think I have to reconnect power to do it. When it is in failure mode, the Mac system profiler can still see the USB device.
A couple of weeks or so ago, I updated the FTDI driver and this seemed to fix it. At that time, I also plugged the interface into a different USB port, directly on the Mac, so that could also have helped.
I have recently upgraded to Yosemite but the problem started just before that. I just updated to 6.0.18 last night and the latest failure started a couple of hours later, but I suspect that is a coincidence.
Of course, this could be an interface hardware problem but it feels more like software since the computer can still see the interface and it works normally for long stretches. I have a hunch that it could be a driver issue but I don't know why it would have started all of a sudden.
I really hate to buy another interface before I have some confidence that it is indeed a hardware problem. If I do get a replacement, should I get the same device? (I need Insteon and X10).
Any suggestions? Anyone else having similar problems?
Thanks!
