title: ADB is not recognizing Samsung S21 when connected with USB
body: <p>When I connect the S21, it only shows information that it is charging, but no prompt for accepting the computer etc.</p>
  <p>I am using Ubuntu.</p>
  <p>USB debugging is active, and ADB is installed. Tried two different computers and two cables. lsusb does not show the device, neither does adb devices. Also tried adb kill-server followed by adb start-server.</p>
  <p>Any ideas?</p>
