If software capture is a pain maybe hardware can help. https://www.bugblat.com/products/ezsniff/index.html[1] or https://www.bugblat.com/products/minisniff/index.html[2] Seems like they are around $100 including shipping. Not exactly cheap but if it works and saves you hours of wasted time .... There is always ebay to sell it once you are done :-) I am sure there are other solutions as well. -------- [1] https://www.bugblat.com/products/ezsniff/index.html [2] https://www.bugblat.com/products/minisniff/index.html
