Edimax EW-7711UMn v1

Overview
1T1R SISO

"PN: 1244-583-01Z" is silkscreened on the board.

The FCC test report lists the following models as identical..
 * Edimax EW-7711UMn, GWU-H11Mn
 * OvisLink AirLive WN5200USB
 * Corega CG-WLUSB10
 * PCI GW-USMini2N (Planex GW-USMini2N)
 * 2 Direct WL0049
 * Unicorn TW-1100N
 * Logitec LAN-WN11/U2
 * AL XM-200U
 * Planet WNL-U554
 * Some of these actually have a different chip type, maybe because a newer/older revision of them is not identical to this Edimax dongle.
