This dongle is intended (and sold for) use with Sony's Blu-ray Disc players and TVs.
"8WUSND06S2A1G" is silkscreened on the board in the FCC photos. This would seem to indicate Alpha Networks manufacture..
The device has the regdomain of 0x6a (World roaming) in the EEPROM.
This adapter uses AR7010+AR9280 (and presumably also the UB94 reference design for that chipset), which is found on a few other devices. It is, however, not likely that any alternative adapters will be usable with Sony products.

- any recent release of the Linux kernel, when using the ath9k_htc driver
