USB B connector pin out is mirrored. Pin 1 is top right, Pin 2 is top left, Pin 3 is bottom left and Pin 4 is bottom right. http://www.usb.org/developers/docs/usb_20_092407.zip (9.7MB spec) - see figure 6.8 on page 96 of USB_20.pdf.

Yes, the USB B connector pin designation shown here is wrong in all graphs. The numbering is counterclockwise starting with pin 1 at the top right diagonal edge, viewing the pins. See: http://www.usbman.com/Guides/BelkinMotherboard_cable_assembly.htm - However, since there are male and female versions of A and B connectors, it might be useful to specify the type and the viewing position. —Preceding unsigned comment added by 118.167.157.23 (talk) 20:01, 14 November 2008 (UTC)
