Error 5002 not being reported in LabRecorder or BioSemi app

[madjens]

The BioSemi amplifier can lose connection to the computer due to physical problems with the hardware. Once such error is the Error 5002 that is shown using the ActiView software as

Possible reasons: unsupported speedmode.
OR
Intermittent data loss (optical cable)
OR
USB driver not closed properly.

When you use the BioSemi LSL app however, this error is not reported. I am not sure if it is a general problem for more errors, but it would be very valuable if the biosemi App throws this error to the end user so they know that data is not being recorded. As it is now, nothing is shown in the LabRecorder terminal. I am using the Windows version of the BioSemi app.

If you are using the ActiView software it is reported and you can react accordingly.

Hmm. This is one of the oldest apps that Christian made for SCCN way back in the day. It looks like there is some infrastructure in place to handle errors on Windows (https://github.com/labstreaminglayer/App-BioSemi/blob/master/biosemi_io.cpp#L23-L43) but there doesn't seem to be any implementation of this on the app side.

It would be nice if BioSemi would hop on the LSL bandwagon and support LSL natively like most other vendors do these days. Otherwise, someone with access to the hardware will have to donate the devel time.
