Reporting transmission error rate/retransmissions?

[WinkelCode]

I've been looking for a way to monitor USB connections for errors, the "Isochronous" and "Bulk" transfer types do CRC error checking and will usually ask for a retransmission when encountering an error. Unfortunately there doesn't seem to be any program that provides an interface to report statistics on that. For example, the nvidia-smi tool can report errors in the PCI-E connection with the graphics card.

Is such a thing feasible to implement here?

If you can get the information, you can present the information. Your best luck is looking at the source, having a device causing enough such errors and creating a pull request.
