Sony Ericsson HS-USB Android Serial sa0101 (COM104) Driver

The Sony Ericsson HS-USB Android Serial sa0101 (COM104) driver helps Windows recognize the USB serial interface exposed by a compatible Sony Ericsson Android device. It is intended for users whose device appears as an unknown USB device, has a driver warning in Device Manager, or needs a working serial connection for compatible service or diagnostic software.

Key Features

• USB serial recognition: Allows Windows to identify the device’s serial interface so compatible applications can communicate with it.
• COM-port access: Supports communication through a Windows-assigned serial port. COM104 is the port shown in this device name; the assigned number may differ on another computer.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches both your Windows version and its 32-bit or 64-bit architecture.
• Interface-specific support: This USB driver listing identifies Qualcomm Atheros as the vendor. Confirm the hardware ID before installation, since a similar device name alone does not guarantee compatibility.

How to Install Sony Ericsson HS-USB Android Serial sa0101 (COM104) Driver

1. Check the device details. Connect the device using a reliable USB data cable, then open Device Manager. Locate the serial interface or unknown device, open Properties, and check Hardware Ids under the Details tab.
2. Choose a matching package. Before starting your Sony Ericsson HS-USB Android Serial sa0101 (COM104) driver download for Windows, verify the supported hardware IDs, operating system, and architecture. For Windows 10/11 searches, note that Windows 11 is not included in this listing’s supported OS range.
3. Download and extract. Choose a trusted source for a free download, and extract the files if the package is compressed. Look for the latest version compatible with your hardware rather than assuming every newer release will work.
4. Install the driver. Run the included installer, if available. Otherwise, right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Do not bypass Windows security warnings for an unverified package.
5. Verify the connection. Reconnect the device or restart Windows if prompted. Check that the interface appears without a warning icon, then select its assigned COM port in your compatible application.

Keep a copy of the working driver before you update. An update may resolve recognition or connection problems, but install only a verified, compatible release; a stable serial connection does not necessarily need the newest available package.
