    Suggestions for a UPB Powerline Interface

    Are any UPB Powerline Interfaces (PIM) better or worse than any others? I'll probably go serial port as I here there are some problems with the USB variety. That's O.K. because I just added an 8 port serial card.

    Lets see, you have PCS, HAI, Simply Automated, etc..

    Most of them are based off the original PCS design, so I have not seen any issues with one over the other.

    The issue with the USB devices is actually a Windows issue where Windows has problems with the power going out on an HID device without the device actually being disconnected.

      So if power is lost at the outlet where the USB PIM is plugged in, then Windows will have problems with the communication (and HS will be hosed until Windows is restarted). Sounds like I spent a lot of money on a USB PIM for no good reason, then...

        This appears to be an issue with at least one brand of UPB PIM. The same is true for the Insteon interface I'm working with.

          Sounds like a Windows "power-save" feature. There has to be a way to turn that off in Windows.

            The power save can be disabled in the USB Root Hub. But I am not sure if that fixes the issues. I am using the Insteon PLC but this may apply.

            I found the following MS DevCon utility, which is a command line interface into Device Manager. You can use it to disable the USB HID interface and re-enable via a batch file, if that resolves your problem.

            http://support.microsoft.com/default...;EN-US;Q311272

            You can get a list of device drivers using "devcon status *". To disable a device driver you would enter "devcon disable <id>" where id is the driver id. The id is USB\VID_10BF&PID_0004\5&36C701F9&0&2 on my system, and you can enter wildcards like "devcon disable USB\VID_10BF*" as long as the id is unique.

            I haven't had a failure since I found this, when/if I do I will test and post results.
