New 802.11ac MT7612U adaptor - PIX-LINK LV-UAC04
I was walking in a mall with shops selling lots of stuff from China and then this PIX-LINK LV-UAC04 drew my attention (interestingly official website doesn't have it)
Below is the lsusb
details from my Chromebook (I don't have other Linux PC with me due to traveling now):

Though I haven't tested it now but first impression is good, can be recognized by Chromebook is a positive signal, with USB3 support means it won't have the 480Mbps speed limit; However this dongle is flat and a bit wide (looks similar to COMFAST CF-953AX) so you might find difficulties to use on Raspberry Pi if other USB devices connected.
