title: Any usb wifi dongle workable with kernel v5.x?
body: <p>I'm now testing TL-WN722N v3 wifi dongle with RTL 8188eu inside on my Linux EVM board.
  However, I always got kernel panic after execute this command:
  &quot;wpa_supplicant -iwlan0 -D wext -c /etc/wpa_supplicant.conf -B&quot;</p>
  <p>After doing some search, I found it might related to Linux Preempt_RT patch.
  Please refer to the link below:

  <p>Maybe I need to find another wifi dongle to use.
  So, my question is, is there anyone using wifi dongle with no problem on kernel V5.x?
  My kernel is Preempt_RT patched.</p>
  <p>Thanks.</p>
