The OTOair Dongle (COM4) driver helps Windows recognize the Otometrics USB dongle and makes its COM-port connection available to compatible software. It is intended for users setting up the dongle for the first time, reinstalling Windows, or troubleshooting a missing or unrecognized device.

Key Features

  • USB device recognition: Allows Windows to identify the OTOair dongle so compatible Otometrics software can access it.
  • COM-port communication: Supports the connection shown as OTOair Dongle (COM4), helping software communicate through the assigned serial port.
  • Support for older Windows systems: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.
  • Setup and recovery: Installing the appropriate driver can help resolve recognition problems caused by a missing or incompatible driver.

How to Install OTOair Dongle (COM4) Driver

  1. Check your system. Open Windows system information to confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 users, note that Windows 10 is listed as supported, while Windows 11 compatibility is not confirmed here.
  2. Select the correct package. Before starting your OTOair Dongle (COM4) driver download for Windows, verify that the package identifies Otometrics and matches your device and OS. Choose the latest version compatible with your setup; a “free download” label alone does not establish authenticity.
  3. Prepare the installation. Close any software using the dongle and extract the downloaded archive if necessary. Follow the package instructions about when to connect or disconnect the USB device.
  4. Install the driver. Run the supplied installer, if included. For a manual package, open Device Manager, locate the dongle or unidentified USB device, select Update driver, and browse to the extracted driver folder.
  5. Verify the connection. Restart Windows if prompted, then check Device Manager for the dongle and any warning icons. Confirm the assigned COM port in your application settings; Windows may assign a number other than COM4.

Keep the driver updated when Otometrics provides a compatible release that addresses your needs. Before an update, review any installation notes and confirm compatibility with your application as well as Windows. If your current setup works reliably, avoid replacing it with an unverified package simply because it claims to be newer.
