Maybe dmesg will give us an answer. Here is an example for an EDIMAX EW-7711UAN (mt7601u)
ID 7392:7710 Edimax Technology Co., Ltd Edimax Wi-Fi
[ 2592.678152] mt7601u 1-1:1.0: ASIC revision: 76010001 MAC revision: 76010500

[ 2593.348899] mt7601u 1-1:1.0 wlp0s20f0u1: renamed from wlan0
...
here we started $ sudo hcxdumptool --check_driver -i wlp0s20f0u1
[ 2730.270596] device wlp0s20f0u1 entered promiscuous mode
here we terminated it
[ 2730.290500] device wlp0s20f0u1 left promiscuous mode
If everything's fine, your dmesg should look like this after the device was plugged in and hcxdumptool's driver check was started.
BTW:
The AC600 is running an old chipset
EDIMAX AC600: EW-7811UAC (RTL8811AU)
ID 7392:a812 Edimax Technology Co., Ltd
"The 8811 chipset uses 8821au, and both that and 8814au uses an old HAL (from v5.1.5) and will never be as good as 8812au has until realtek releases newer HAL's"

This device doesn't work well if plugged into an USB 3.x port (xhci issue).
