+## Control-only
+
+Note that the purpose of OTG is to control the device without USB debugging
+(adb).
+
+If you want to solely control the device without mirroring while USB debugging
+is enabled, then OTG mode is not necessary.
+
+Instead, disable video and audio, and select UHID (or AOA):
+
+```bash
+scrcpy --no-video --no-audio --keyboard=uhid --mouse=uhid
+scrcpy --no-video --no-audio -KM  # short version
+scrcpy --no-video --no-audio --keyboard=aoa --mouse=aoa

+
+One benefit of UHID is that it also works wirelessly.
