There are provisions in our protocol for detecting this kind of data loss. They didn’t make it into the final product but could be added with a software update. Some of our other products drop connection as you describe, the VSG60 will actually drop connection if any issues occur with the DMA xfers, as exposed through the USB API.
The sandy bridge processor is relevant. When we were first developing the BB60A we did development on sandy bridge processors and were never able to get the device to run fast and stable, we found out this was likely due to the Renesas USB 3.0 controllers used during this generation of CPU. The 3rd generation Intel CPUs (Ivy Bridge) started shipping with Intel USB 3.0 controllers and this fixed our stability issues. There is lots of chatter from around that time online (2012) regarding these Renesas controllers. Many companies making high speed USB 3.0 equipment stated to avoid these controllers.
Our user manuals all specify a minimum of 3rd gen Intel processor specifically for that reason, so you have the “Native” Intel USB 3.0 controllers.
You could try installing a USB 3.0 card if possible, there are several that have been tested to work with our products. The startech one has two USB 3.0 controllers on it (one controller for 2 adjacent ports), so it can support two of our devices streaming at their maximum rates.
I released an update to the VSG60 software today that reduces the sample rate on the CW output. It might be enough to be stable on this machine.
