It was only after I refused to bow down and lick his boots in response to whatever fluke gave rise to the infamous 9/10 that he turned nasty. Guess I should have seen it coming.

I do not care to evaluate personal abilities as others do here. Hope it is clear. I asked several very simple question, that's it. I am very much ok with variety of opinions on usb cables and anything in the world. If people do hear difference in usb cables – ok. If they don't - ok. And, I will not be hurry with evaluating such people personally. Teresa 1 Link to comment

In the case of the subject of this thread, practice has shown there is far more to the subject than originally published in textbooks. If USB didn't have any well documented problems with Audio, there would be no need for devices such as USB Regens either. We need to be mindful here too, that such devices are also designed by well qualified designers such as John Swenson etc You aren't the only member of this forum who is capable of designing high performance multi layer PCBs either.

Because you keep quoting your undoubted expertise in this area, neglecting that others such as John are also well aware of RF/EMI control issues in this area too. Even between highly qualified E.E.s and S/W designers it is obvious that there are many areas of disagreement. Only with talking to and learning from other qualified people in this area, will these niggly implementation issues with USB be fully solved, instead of being dismissed as non existent.

It was suggested that the reference given covered this area Can you quote those minimum requirements , as I have seen huge differences in the thickness of compliant USB 2.,0 .cables, where the thinner one died in the arse at around 4M length with a USB memory stick plugged in, and the other worked at much longer lengths with no problems at all.
