Comment 313 for bug 1667750

Stanislaw, are you sure?

Same device, tested on Intel system (xhci unpatched):
Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz
06:00.0 USB controller: ASMedia Technology Inc. ASM1042 SuperSpeed USB Host Controller
07:00.0 USB controller: ASMedia Technology Inc. ASM1042 SuperSpeed USB Host Controller

ASM1042 should be USB3, too - but I'm not sure.

starting antenna test and packet injection test (that can take up to two minutes)...
available channels: 1,2,3,4,5,6,7,8,9,10,11,12,13,14,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,100,102,104,106,108,110,112,114,116,118,120,122,124,126,128,130,132,134,136,138,140,149,151,153,155,157,159,161,165,184,188,192,196
packet injection is working on 2.4GHz!
injection ratio: 35% (BEACON: 176 PROBERESPONSE: 62)
your injection ratio is average, but there is still room for improvement
antenna ratio: 35% (NETWORK: 20 PROBERESPONSE: 7)
your antenna ratio is average, but there is still room for improvement
2 driver errors encountered during the test

terminating...

BTW:
5GHz injection not shown as working, because I haven't set up a 5GHz ACCESS POINT to respond to hcxdumptool
