@zetasyanthis I wonder if usb 3 is different, since it's meant for higher speed stuff
usb 1.1 didn't specify an impedance, i don't think, because it's too slow for impedance matching to really matter
-F
I am going to have to ask on StackExchange tomorrow and hope someone answers.
(Longer, properly worded question = more energy than brain has right now. :P)
@Felthry
No, 2.0 and 3.0 both call out 90 +/- 7 ohms. What on earth. Why would that be different from everything else made? XD
