What To Do When the Huion Driver Shows Device Disconnected or No Devices Connected?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
A persistent "Device disconnected" or "No devices connected" message in the Huion driver usually signals a driver, connection, or permission problem rather than an irreparable tablet — but it can also point to hardware failure; stepwise isolation (cable/port, driver clean reinstall, OS permissions/Bluetooth settings) identifies the cause in most cases [1] [2]. Huion’s official guidance emphasizes full removal of previous drivers and reinstalling the correct version before assuming physical damage, while community reports show that leftover drivers, OS quirks and bad cables are common culprits [1] [3] [4].
1. Identify the symptom and run quick checks
If the tablet lights up or shows the computer wallpaper but the pen doesn't control the cursor and the driver reads "Device disconnected," test whether the pen moves the mouse cursor on the main display — if it does, the problem is the driver, not the hardware [5]; if nothing responds, unplugging and reconnecting cables and trying a different USB port are basic but effective first steps [5] [6].
2. Uninstall every conflicting driver and perform a clean reinstall
Huion warns that multiple Huion drivers or other tablet drivers (Wacom, Lenovo pen features, etc.) can conflict and that users must "completely remove all files and folders associated with the previous tablet driver" before reinstalling the correct Huion package [1] [2]. Official instructions include uninstalling drivers, quitting Huion-related background processes via Activity Monitor/Task Manager, restarting the computer, then installing the correct driver version for the tablet [7] [2].
3. Try driver version changes and port/cable swaps
When reinstalling fails, downgrade to an older driver release or try the latest release specifically matched to the product series (e.g., V12 for certain pressure models) because version mismatches can trigger the "device disconnected" state; switching to another vacant USB port or replacing the cable is frequently successful and recommended by both Huion and troubleshooting guides [3] [6].
4. For Bluetooth or macOS users, grant permissions and check preferences
Bluetooth connections introduce an extra layer: on macOS the Huion driver installer will request Bluetooth permissions and the driver’s Preferences menu may need explicit Accessibility and Bluetooth access for the tablet to bind correctly — reinstall and accept permission prompts if asked [8] [2]. Huion’s European support notes also instruct unlocking Accessibility to grant HuionTablet and TabletDriverAgent access when macOS security blocks functionality [2].
5. Use Device Manager/Scan for hardware changes and look for USB errors
Windows guidance includes using Device Manager to "Scan for hardware changes" and to resolve "USB device not recognized" errors which can masquerade as driver disconnects; conflicts from multiple USB devices or corrupted device descriptors sometimes need driver reinstallation or port changes rather than tablet replacement [9] [6].
6. When the driver fixes fail: consider hardware and support escalation
If the pen cannot move the cursor even after a full driver purge, reinstall, cable/port replacement and testing on another computer, Huion notes that the tablet port or the tablet itself may be damaged and recommends contacting support with detailed logs and device screenshots [1]. Community threads reveal mixed experiences where users were told the tablet was defective while the display still worked — an outcome that advises careful verification on a second computer and insistence on diagnostic steps before accepting device replacement [10] [4].
7. Hidden friction and alternative viewpoints
Official support centers on systematic driver cleanup and OS permissions [1] [7], while community reports stress vendor support gaps and the occasional need to try older drivers or third-party forum solutions when official downloads or instructions don't resolve the issue [6] [4]. Users should be aware that tech-support incentives can favor hardware RMA over longer troubleshooting, so exhaustive isolation steps and documenting tests on another machine reduce the chance of unnecessary replacement [10].
