maybe our tech affine community members want to contribute to a recent discussion Werner and I do about the HackerBus USB connection? Concerns are about mechanical stability of the 3pin header (Mill-Max 851-43-003-30-001000) as well as about signal integrity with a unterminated stub of >5mm length (from the header springs) on DP/DN. Alternatives we look into: Zebra strips (http://www.abatek.com/en/products/connectors.html) or pogopins on user's extension board (http://www.digikey.com/product-searc...4-11-0&stock=1)
