Windows 10 may try to update the driver via Windows Update, breaking pressure sensitivity. To prevent this:
USB Ports: The Bamboo CTH-670 uses a standard USB-A connector. If you are using a modern laptop that only has USB-C ports, you must use a high-quality adapter or hub. Some cheap USB-C adapters do not transmit the data handshake correctly, causing the Wacom driver to fail to recognize the tablet.
The Wireless Kit: Many CTH-670 tablets came with a wireless accessory kit (a dongle and a rechargeable battery). If you are using the wireless kit on Windows 10, ensure the driver is installed wired first. Once the tablet works via USB, you can unplug it and switch the switch to "Wireless." If it disconnects frequently, the battery inside the tablet may be aging and unable to hold a charge, requiring you to revert to wired usage.
Before plugging in your CTH-670, you must clean out any old Wacom or tablet drivers.
Installing a legacy driver on Windows 10 is not as simple as clicking "Next." To ensure the tablet works, you must follow a strict order of operations to prevent Windows Update from interfering. bamboo cth-670 driver windows 10
Step 1: Clean Uninstall (Crucial) If you have previously plugged the tablet in or tried other drivers, you must clean the system.
Step 2: Install the Driver
Step 3: The Connection and Security
Step 4: Restart
First, it is important to manage expectations. Wacom officially stopped updating drivers for the Bamboo series (including the CTH-670) a few years ago. On Windows 10, you will not be using the modern "Wacom Center" software that comes with newer Intuos or Cintiq models. Instead, you will be using the older Wacom Tablet Properties interface.
Because the hardware is older, the drivers are not digitally signed in the way modern Windows 10 drivers usually are. This occasionally causes Windows to flag the driver or attempt to replace it with a generic "HID-compliant device" driver, which breaks pressure sensitivity.
OpenTabletDriver is an open-source, cross-platform driver that breathes new life into old tablets. It fully supports the CTH-670 on Windows 10/11.
After restarting, look for the Bamboo Dock or Bamboo Preference Tool icon in your system tray (near the clock). Windows 10 may try to update the driver
Test 1: Pen Pressure
Test 2: Multi-Touch
Test 3: Application-Specific
If all three tests pass, you have successfully installed the Bamboo CTH-670 driver on Windows 10. Step 2: Install the Driver
If you don’t need pen pressure or touch gestures, the tablet works as a basic HID mouse/pen device without extra drivers. Pressure-sensitive apps (drawing, photo editing) require the 5.3.5-3 driver.
