In the "USB-A/B" section, they're all labelled "Type-A", the 3rd and 4th should be labelled "Type B". It's also missing - mini-b 4 wire (older phones, etc) -

In the "USB-A/B" section, they're all labelled "Type-A", the 3rd and 4th should be labelled "Type B". It's also missing - mini-b 4 wire (older phones, etc) - micro-b 4 wire (most electronics prior to type c) - micro-b 8 wire (mostly seen only found on external 2.5" HDDs) There were also a bunch of other connectors (mini-a, mini-a/b, etc) but they are very rare.
