vn::timeout Error Occuring

[advra]

This is a common occurrence where I cannot connect to the VN. I am using a VN200 to log data of a period of time.

This is occurred on 3 separate occasions: one when the VN is left connected to the USB port of a raspberry pi for roughly a couple days and twice when our logging program crashed. Below is the error we get:

terminate called after throwing an instance of 'vn::timeout'
  what():  timeout
Aborted

The immediately solution is to replug the USB so we can connect to it again. Any idea why this is? Ideally I would prefer not to manually reset the USB as the device is remote during long periods of time. I look forward to any suggestions or insight you may provide.

I just had the same and in my case it was usb issue of the devices and has nothing to do with the ros driver.

There are ways to reset the USB ports in software. I believe you can even power cycle them.
