Public bug reported:
I'm trying to connect multiple WiFi cards through powered USB hubs but
unfortunately some logic does detect them in lsusb but doesn't create
appropriate ammount of interfaces. Additionaly from 3 connected TP-Link WN722N
cards only one have light blinking what's usually means firmware was loaded
properly. Also serial numer is constant 12345 for all 3 tplink cards:
[11299.508388] usb 2-1.4.1.2: Product: USB2.0 WLAN
[11299.508391] usb 2-1.4.1.2: Manufacturer: ATHEROS
[11299.508394] usb 2-1.4.1.2: SerialNumber: 12345
