Bluescreen in USB-serial driver [solved - unrelated to AquaSuite]

Sonntag, 16. März 2025, 06:25

I have twice in the last couple of months had bluescreens (DRIVER_IRQL_NOT_LESS_OR_EQUAL with a bug check code of 0xd1) in the CH341S64.sys driver. Given it's a USB-serial driver often used by Adruino, I suspect this is installed/used by AquaSuite -- and believe I have confirmed this by uninstalling the Aquasuite, rebooting, manually uninstalling the driver, and rebooting and confirming its gone. Then installing AquaSuite again, and the driver re-appeared.

I have only seen this with CH341S64.sys v 3.90, which was released in October last year. I suspect the issue was introduced then.

Can I safely roll-back the driver version? Does Aquacomputer have any insight here? At this point I have uninstalled the software, I really don't like instability!
Details:
Problem Event Name: BlueScreen
Code: d1
Parameter 1: 38
Parameter 2: 2
Parameter 3: 0
Parameter 4: fffff8074b2448a1
OS version: 10_0_26100
Service Pack: 0_0
Product: 256_1
OS Version: 10.0.26100.2.0.0.256.48

Locale ID: 2057
Looking at: https://learn.microsoft.com/en-us/window…t-less-or-equal - parameter 1 is defined as the memory referenced. 38 isn't a valid address, so this looks like a null pointer that is de referenced.

None of our devices uses a USB to serial interface and therefore this driver issue has nothing to do with the aquasuite. So, do whatever you want to do with this driver: downgrade, uninstall etc.

I use Arduino IDE and CircuitPython to write code for various micro-controllers, some of which have USB to serial chips on them. My Windows 10 system has CH341S64.SYS and CH343S64.SYS installed, and Aquasuite X.82. I have not had any Bluescreens. The version of CH341S64.SYS I have installed is v3.9.2024.9 with release date Sept 16, 2024. f the version of CH341S64.SYS you have installed was released in October 2024 it must be a later version than the one I have installed. There are many kinds of devices that could be causing this driver to be installed. Since Aquacomputer has confirmed that Aquasuite does not install this driver, you should consider what else could be causing it to be installed. Any of the following could be the culprit.

USB to DB9 Serial Adapter
3D Printer or CNC Machine
Automobile OBD-II to USB Adapter
Logic Analyzer or Oscilloscope with USB
USB External Storage Drive
USB to SATA Adapter
Gaming Console Accessory
Ham Radio with USB Interface
Bluetooth/WI-Wi-Fi Adapter
Bluetooth Dongle

Okay thanks for all the information and sorry for the false alarm. I'll keep digging.

Ah I had an mmWave sensor device connected which uses an ESP32. That's to blame for this, nothing to do with AquaSuite!
Thank you!

Some ESP32 MCUs have a USB to Serial chip on board that could cause that driver to be installed. It does not explain the Bluescreens. You could try installing the previous version and see if that stops the error.
