Sony Vaio Bluetooth Laser Mouse Vgp-bms33 Driver -

Sony officially discontinued the VGP-BMS33 driver support around 2014 after spinning off its Vaio division. The original driver was hosted on Sony’s eSupport website, but those links are now dead. The driver package is typically named:

A. Try automatic (recommended)

B. Use Device Manager if automatic fails

C. Manual driver from Sony or adapter vendor Sony Vaio Bluetooth Laser Mouse Vgp-bms33 Driver

Before diving into drivers, it is crucial to understand what the VGP-BMS33 is—and what it is not.

Unlike standard USB dongle mice, the BMS33 uses Bluetooth 2.0. On original Vaio laptops, Sony pre-installed proprietary Bluetooth stack software (often from Toshiba or Broadcom) and specific mouse drivers to unlock full functionality—particularly the side buttons and tilt-wheel.

Without the correct driver, the mouse will work as a generic HID (Human Interface Device), but the extra buttons will be dead. In the mid-to-late 2000s

| Problem | Solution | |---------|----------| | Mouse not found in Bluetooth scan | Press Connect button again (5 sec). Remove from paired list and re-pair. | | Connects then disconnects | Replace batteries (2× AA). Low power interrupts Bluetooth. | | Laggy pointer | Move mouse closer to PC. Remove USB 3.0 devices nearby (interference). | | Not working after sleep | Disable Bluetooth power saving: Device Manager > Bluetooth adapter > Power Management > uncheck “Allow computer to turn off this device”. | | Works, but side buttons do nothing | Test in different app (browser). Use X-Mouse Button Control (free) for remapping. |
