Disk Array USB Port (COM33) Driver

The Disk Array USB Port (COM33) driver helps Windows recognize the USB-connected serial interface on compatible Dot Hill disk array hardware. It is intended for administrators and users who need to connect to the array’s management or service port, rather than access stored files directly. If the port is missing or appears with a warning in Device Manager, installing the appropriate driver may restore communication.

Key Features

• USB serial communication: Enables compatible management or terminal software to communicate with the Dot Hill array through a virtual COM port.
• Device recognition: Helps Windows identify the interface instead of leaving it listed as an unknown USB device.
• Legacy Windows support: Supported operating systems listed for this device are Windows 10, 8.1, 7, Vista, and XP; verify that the individual driver package matches your system.
• COM port configuration: Makes the interface available for serial connection settings in Windows. COM33 is the assigned port number, which may differ between computers or change after reconnection.

How to Install Disk Array USB Port (COM33) Driver

1. Check your system and hardware. Confirm your Windows edition and whether it is 32-bit or 64-bit. In Device Manager, check the device’s hardware IDs to help identify a matching package.
2. Choose a compatible package. Before starting a Disk Array USB Port (COM33) driver download for Windows, review the supported operating systems and hardware details. Select the latest version confirmed to support your device, and use a trusted free download source.
3. Prepare the connection. Follow the package instructions for when to connect the array’s USB service cable. Avoid interrupting active management tasks while replacing an existing driver.
4. Install the driver. Run the included installer, if provided. Otherwise, open Device Manager, right-click the device, choose Update driver, and browse to the extracted driver folder. Restart Windows if prompted.
5. Verify communication. Check that the device appears without a warning under Ports (COM & LPT). Select the assigned COM port in your management software and use the connection settings specified in the array’s documentation.

Keep the driver updated when a compatible release addresses connection problems or supports your Windows environment. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed for this device, but Windows 11 support is not confirmed here. Before an update, retain the previous working package so you can roll back if needed.
