I just tried with one controller (my laptop, running pox with info.packet_dump and forwarding.l2_learning) connected to both switches. A host connected to switch A (host 1) was pinging a host connected to switch B (host 2).
According to the packet dumper, switch B sees the arp request from host 1 and the arp reply from host 2, and pox installs a flow on switch B from host 2's port (port 1) to the wireless port (port 5). But switch A never sees the arp reply and neither does host 1. This is probably not an issue with switch A. When I connect a wireless client (Ubuntu 12.04 PC with cheapie rt2800usb adapter) to switch A's SSID, packets flow as expected.
