Error -1073807360

[mtimnak]

Hello,

I have a general question about how/if I can get more information about an error code (-1073807360). The Message that comes with this code is "VISA Write in microController_Comm.vi"

To provide a bit more context: This error occurs sporadically, and without a clear cause. I have a VI that communicates with a Teensy microcontroller about 50 times a second. Each communication step involves a write, followed by a read. When the error first occurs, the microcontroller times out for about 3-4 minutes, then normal functionality returns.

I have searched the web for a more detailed description of this error code to no success. Any help or suggestions would be greatly appreciated!

Thanks,

Matt

Unknown Error...those are fun to figure out...

What are you using to talk to your device?  I'm guessing a USB-Serial converter that is then using RS-232 to talk to your microcontroller.  With that assumption, a couple of things I would look at:

1. Make sure you have the latest driver for the converter.

2. Go into your computer's device manager and go into the settings for every USB hub.  There is a Power Management or similarly named tab that has a checkbox to allow the computer to turn off the bus to save energy.  Turn that off.  This has been known to randomly turn off and back on many different devices.
