USB KVM
SuperKVM USB KVM hardware—video capture plus HID control, U-disk direction switching, Web OTA, and USB / LOOP / Pro differences.
USB KVM Answer first: SuperKVM USB KVM captures the target HDMI picture while injecting keyboard/mouse HID over Target USB, replacing display + keyboard + mouse. Supported models also offer browser U disk direction switching and Web OTA. USB / USB LOOP / USB Pro mainly differ in capture and loop out specs—see the comparison guide.

If upgrade fails, retry by re operating the page or restarting the device, usually will succeed. OTA failure has no impact, because the system uses dual partition verification mechanism, upgrade failure will not affect the correct firmware OTA File Download: When there is a firmware update, the webpage will show a new version prompt, click the red new version number, and it will jump to the download page, download the corresponding OTA bin file. Select OTA file: After selecting OTA file successfully, click 「Download」 button: Upgrade successful: If repeated upgrades fail, contact the developer, export the upgrade log and send it to the developer for confirmation Restart KVM Through button 8 internal menu 「Restart Device」, click to restart KVM hardware Mouse Micro movement Through button 8 internal menu 「Mouse Micro movement」, after enabling, if KVM client has no keyboard/mouse input for more than 30s, KVM device will simulate sending mouse data every 30s to ensure target host does not sleep Modify Mouse Keyboard Device VID PID Through button 8 internal menu 「USB vid pid」, can modify target mouse keyboard VID PID, can also modify host CDC device VID PID UVM32 app Download UVM32 app download is now supported. Users can download compiled apps via the web, and after download they can run immediately without restarting Control PC Through Tablet or Phone Requires Bluetooth accessories, pe
