upgraded MW to 1.30 - maybe things are slightly less broken
D-Link DWA-171 rev A1
Wireless AC Dual Band USB Adapter
"Ver:A0-0'13/01/10" (or something like that) and "Made in China"
- is silkscreened on the board in the FCC photos.
- driver set for the 8812au has a USB ID of 2001:3314..
This device would appear to have been listed in a MediaTek driver
- set with a 2001:3d02 (USB\VID_2001&PID_3D02) USB ID.
I suppose this adapter was orignally slated to use MT7610U.
