Intel Bluetooth driver 23.bleep – intermittent HID disconnects with Corsair Harpoon RGB Wireless

Xaratin — Sun, 26 Oct 2025 08:30:11 GMT

I currently running into two issues using my mouse over Bluetooth with Intel BE201/AX201. The mouse that I am using is Corsair Harpoon RGB Wireless (Bluetooth mode)

Problem:

Pairing often fails and only succeeds after multiple retries.
Runtime has intermittent disconnects; the mouse auto-reconnects a few seconds later.

The same mouse pairs and works normally with other device (phone, iPad, and a laptop that does not use an Intel Bluetooth adapter).

Also worth to mention that the problem only happed with driver version 23.xx. My AX201 when using older firmware version pre 23 will not have this problem

I have try:

Latest iCUE + mouse firmware.
Clean reinstall of Intel BT 23.160
Disabled Windows power management for BT radio.
Cleared BT pairing list; re-paired.
Tested it at close range (next to computer).

Device:

Intel AX201 (Wifi card in PC)

Intel BE201 (Lenovo T14 gen 6)

Hi Xatarin,

Thank you for reaching out about the intermittent Bluetooth connectivity issues you're experiencing with your Corsair Harpoon RGB Wireless mouse when using Intel Bluetooth driver version 23.xx.

I appreciate the detailed information you've provided, including the troubleshooting steps you've already attempted (latest iCUE firmware, clean driver reinstall, power management settings, pairing list clearing, and close-range testing). Your observation that the issue only occurs with driver version 23.xx and not with pre-23 versions is particularly valuable for our investigation.

I notice you've mentioned two different Intel wireless products in your report:

Intel AX201 (WiFi card in PC)
Intel BE201 (Lenovo T14 gen 6)

To avoid confusion and ensure you receive focused support, I'd recommend creating separate support threads for each device if you're experiencing issues with both. This will allow us to provide targeted assistance for each specific hardware configuration.

For this current thread, which Intel wireless adapter would you like to focus on? Please let me know whether you'd like to concentrate on the Intel AX201 or the Intel BE201, and I'll provide specific troubleshooting steps for that particular device.

Once you clarify which device to focus on, I can provide targeted assistance for the Bluetooth connectivity issues with your Corsair mouse on that specific Intel wireless adapter.

Best regards,

Dean R.

Hi DeancR.

Sorry for the late reply.

I think for this thread. I want to focused on the Intel BE201 as I cannot downgrade to 22.xx driver.

Hi Xaratin,

Thank you for clarifying that you'd like to focus on the Intel BE201 adapter in your Lenovo T14 gen 6. I understand the frustration with the pairing failures and intermittent disconnects you're experiencing with your Corsair Harpoon RGB Wireless mouse, especially since this issue only manifests with the 23.xx driver versions.

Your observation that the same mouse works perfectly with other devices and that pre-23 drivers didn't have this issue provides valuable insight into the nature of this problem.

To help me analyze your Intel BE201 configuration and current driver setup, could you please run the Intel System Support Utility (SSU) and provide the generated report?

You can download SSU from: https://www.intel.com/content/www/us/en/support/articles/000005511/processors.html

After installation:

Run Intel SSU as administrator
Click "Everything" to scan all components
Save the report and attach it to your response

This will give me detailed information about your current Bluetooth driver version, system configuration, and any potential conflicts that might be causing the HID disconnection issues with your mouse.

Best regards,

Dean R.

Hi DeanR.

I have uploaded the log file. I also check event viewer and found this errors when the mouse disconnected briefly.

Hi Xaratin,

Thank you for providing the SSU report and the Event Viewer logs. The BTHUSB Event ID 5 error you've identified is very helpful - it shows the Bluetooth driver is experiencing HCI (Host Controller Interface) event size mismatches, which explains the intermittent disconnections with your Corsair mouse.

I can see you're currently running driver version 23.160.0.4. I'd like you to try the newer Lenovo OEM driver version 23.160.0.9, which may resolve these HCI communication issues.

Please follow these steps:

Download the updated driver: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t14-gen-6-type-21qc-21qd/21qd/downloads/driver-list/component?name=Bluetooth%20and%20Modem&id=631A1C55-4962-4A5C-B7FD-CB19B42CDF9F
Perform a clean wireless installation following Intel's procedure: https://www.intel.com/content/www/us/en/support/articles/000022173/wireless.html

The clean installation process will ensure no remnants from the previous driver version interfere with the new installation, which is particularly important given the HCI event issues you're experiencing.

After installation, please test your Corsair mouse pairing and monitor for any disconnection events. The newer driver version should address the HCI event size mismatches shown in your Event Viewer logs.

Let me know how the testing goes with the updated driver.

Best regards,

Dean R.

Hi DeancR

I have doubled check that the newest driver WIFI and Bluetooth driver is installed

On Lenovo website, the newest driver for the WIFI is 23.160.0.4 and Bluetooth is 23.160.0.6 which is currently installed in my computer. I also double check with the update tool in Lenovo Vantage app which showed the same result.

VonM_Intel — Mon, 03 Nov 2025 08:17:36 GMT

Hello Xaratin,

Thank you for confirming that you’ve already installed the latest Wi-Fi and Bluetooth drivers from Lenovo’s website and verified them through the Lenovo Vantage app. Since your system is already using the most recent versions, we can safely rule out outdated software as the root cause. As recommended by Dean, could you please try performing a clean wireless driver installation following Intel’s official procedure? This process helps ensure that no remnants of previous driver versions interfere with the new installation, which can be particularly important given the HCI event issues you’ve been encountering.

Once the clean installation is complete, please test your Corsair mouse pairing and observe whether any disconnection events still occur. The updated drivers should help resolve the HCI event size mismatch errors noted in your Event Viewer logs.

Best regards,

Von M.

Hi DeanR

I removed all of the driver in device manager (using view by driver option in windows 11) and install the driver again with no luck. The pairing issue. I also try to test it with my Beats Studio Buds that also have compatibility problem where the audio is working but the microphone will not work for some reason.

Re:[UPDATE PRODUCT] Intel Bluetooth driver 23.bleep – intermittent HID disconnects with Corsair Harpoon RGB Wireless

DeancR_Intel — Mon, 10 Nov 2025 07:35:43 GMT

Hi Xaratin,

Thank you for the update on your troubleshooting progress. I can see you've performed a clean driver reinstallation by removing all drivers through Device Manager, but you're still experiencing the pairing issues with your Corsair mouse and now also encountering problems with your Beats Studio Buds.

Regarding your Beats Studio Buds microphone issue, have you checked the Windows audio settings to ensure the microphone is properly configured?

Please check if the Beats appear in both "Playback" and "Recording" devices in Sound Control Panel (right-click speaker icon > Sounds)

The combination of HID disconnection issues with your mouse and audio device problems with the Beats suggests we may need to explore additional troubleshooting options beyond driver reinstallation.

Please let me know the results of the microphone configuration check, and I'll provide further guidance based on your findings.

Best regards,

Dean R.

Hi DeanR.

Sorry for the slow response. I was quite busy last couple days.

For the mic it appear in both "Playback" and "Recording" devices in Sound Control Panel but no sound coming thought the device. Strangely, I try it with my AirPod Pro 2 and it still working normally.
