Tenda W522U

Overview
The file name of the Linux driver (included in the driver download
 * from the Tenda site) indicates that this device uses RT3572.

The adapter is shown as using two Skyworks (SiGe) SE2595L
 * (Dual Band 802.11n WLAN Front End IC) in the FCC photos.

Assumed C8:3A:35 (Tenda) OUI (shown in the FCC external shot,
 * though barely.. it's also the only current Tenda OUI)

This product listing on newegg makes the claim that this adapter is an alternative to the Samsung WIS12ABGNX for use with certain Samsung TVs. That's not too surprising since they use the same chipset and likely have the same USB IDs.
