microUSB-B is as it were standard with the phones and tabs, so nobody posts about microUSB-A

microUSB-A is provided for small devices that act as an USB host.

Most of the phones act as USB client.
Now, some phones can act as client and as well as host (USB On The Go).
For to act as USB host they need an USB OTG cable. These cables have a microUSB-B connector too, but its ID-pin is jumped to 0V. So the phone "sees" microUSB-A and will switch in USB host mode.
