The BT52 is a (assumed) Bluetooth/PS/2/USB wireless mouse model name often used generically; available documentation and driver support vary by manufacturer. This guide covers how to identify the exact device, obtain and install drivers for Windows, macOS, and Linux, troubleshoot common issues, and where to find firmware or replacement software.
BT5.2 mouse drivers operate across several platforms to maintain the Bluetooth LE (Low Energy) stack:
This paper documents the process of developing a mouse driver for a BT52-based pointing device. The BT52 chipset implements the standard PS/2 mouse protocol with three buttons and optional scroll wheel support. The driver is developed for a bare-metal x86 environment and later ported to a Linux kernel module. Key challenges included timing synchronization, interrupt handling, and interpreting the byte stream from the device. The resulting driver achieves low-latency cursor control and demonstrates the feasibility of supporting legacy chipsets in modern systems.
For most users, a "BT5.2 Mouse" is a generic identifier for a Bluetooth Low Energy device. You can find drivers through the following channels: Official Manufacturer Sites : This is always the safest bet. Official HP Support Page
, you can use their innovative "Web Cloud Driver," which works directly in your browser without needing an installation. Third-Party Repositories : Sites like DriverIdentifier DriverScape host generic drivers for specific hardware IDs (like BTHLE\GENERICDEVICE ) used by Dell, Lenovo, and Samsung laptops. Microsoft Store : Apps like Bluetooth Mouse Driver Updater
(e.g., Intel or Realtek Bluetooth drivers) rather than the mouse itself. Customization
BT52.COM driver.AUTOEXEC.BAT to load it with parameters like /IRQ=3.vetusware.com or archive.org). Getting it to work in DOSBox would be a fun, if pointless, challenge.
