¶ Universal ECG Bus Controller Driver Incompatibilty
¶ Issue
On some systems running Windows 10 version 21H2 (and above) with newer USB 3.2 chipsets (such as the latest HP mini desktop PCs) your QRS Diagnostic Universal ECG device may not work. Upon looking further into the issue, you may see an exclamation mark next to the Universal ECG Bus Controller device in Device Manager. This article can help with this specific issue.
Note: this article only applies to the QRS Diagnostic ECG devices with original manufacturers' USB trunk leads and does not apply to ECG devices originally using a serial port-based trunk lead (with or without a seperate connected USB to Serial adaptor cable), or any ECG devices converted to USB by any non-original USB trunk lead.
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
{Bad Image}%hs is either not designed to run on Windows or it contains an error. Try reinstalling the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0x
This error is caused by an incompatibility between the older QRS Diagnostic / Vectracor USB drivers and some newer systems. As the QRS Universal ECG device uses an FTDI USB to Serial chipset, we can use another driver to work around the problem. Please follow these steps.
¶ Solution 1 (recommended)
1. Download the latest QRS Diagnostic device drivers (as packaged with Office Medic version 6.1.0 and works with Office Medic version 5.8 and up)

3. Check the device manager to ensure the devices appear in the list without warning or error icons next to them.
