Is the ASUS USB-AC53 WLAN adapter supported?

I have just purchased an ASUS USB-AC53 USB WLAN adapter.

This adapter identifies itself as follows:

ugen0.2: <Realtek 802.11ac NIC> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0210 
  bDeviceClass = 0x0000  <Probed by interface class>
  bDeviceSubClass = 0x0000 
  bDeviceProtocol = 0x0000 
  bMaxPacketSize0 = 0x0040 
  idVendor = 0x0b05 
  idProduct = 0x184c 
  bcdDevice = 0x0210 
  iManufacturer = 0x0001  <Realtek>
  iProduct = 0x0002  <802.11ac NIC>
  iSerialNumber = 0x0003  <123456>
  bNumConfigurations = 0x0001 

There's a match for this driver in /usr/src/sys/contrib/dev/rtw88/rtw8822bu.c:

        { USB_DEVICE_AND_INTERFACE_INFO(0x0b05, 0x184c, 0xff, 0xff, 0xff),
          .driver_info = (kernel_ulong_t)&(rtw8822b_hw_spec) }, /* ASUS U2 */

but if I load rtw88, nothing happens.

Is there any step I'm missing to make this adapter work?

Yours,
Robert Clausecker
