InSSIDer with MetaGeek Plus supports a variety of USB adapters. As of this posting, MetaGeek recommends and sells the Edimax EW-7833UAC AC1750
Chanalyzer only recognizes USB Wi-Fi adapters with the their standard Windows drivers installed. By default, the only drivers available to Windows for the Edimax adapter are for monitor mode, which captures all Wi-Fi traffic on a channel. In that mode, the Edimax does not listen to all channels for network announcements (called Beacons). Those Beacons are the only Wi-Fi data that Chanalyzer uses, so it just uses the built-in Wi-Fi adapter in standard operating mode to collect them.
