Hello,
I am using newlib gEDA footprints from www.luciani.org
( pcb-symbols-jcl_2006-8-20.tgz).
I am not sure if pin- numbering of USB-Type-B connector called
CON_USB_TYPEB__Keystone_924 is correct. I have an identically
looking connector from www.reichelt.de (Assmann). This connector
is wired internally without crossing wires, which is the
simplest way. Internal wiring of CON_USB_TYPEB__Keystone_924 is
not shown at Keystone homepage, but I think it should be
identical to my connctor.
So I think that pin-numbers of CON_USB_TYPEB__Keystone_924 are
wrong, V+ is exchanged with GND and D+ is exchanged with D-.
Has someone used the Keystone 924 USB-Connentor and can tell me
if my assumption about exchanged pins is right or wrong?
Best regards
Stefan Salewski
The keystone pins and contacts are numbered:

I think those numbers are standardized. See section 6.5 of the USB
spec or chapter 19 of USB Complete.
I've used that footprint with a generic "B" connector and it worked OK.
Regards,
Mark
